The Pandemic is Over

This is my prediction that by the end of February or maybe March, as more and more of the population gets infected. However, due to the confusion promoted by the news reporters, as well as social media and changes seen in most pandemics the population has become confused.
All of a sudden there is the push to use N95 and KN95 masks as the effective face protection.
But listen here, the use of N95 and KN95 masks were always the most effective, but the scientists were “silenced” and as long as you were wearing some sort of face masks or facial coverings “everyone” was satisfied. But listen carefully, the cloth and paper masks never were and protection from any virus. Remember that viruses are measured in microns, not inches or millimeters, etc.
Also, as Omicron takes over, we are seeing the effects and power of the portion of the vaccinated. Yes, they will get sick, but many will be asymptomatic and therefore will never be counted as infected. Which is my biggest problem with the Administration sending out millions of home self-tests. So, they are going to send out 500 million to a population of about 400 million people, which means that you can use the test once. Many times, the tests will be read as negative due to the timing of the infection and then what.
Also, with self-testing, if your tests are positive, who will report their positive tests? Therefore, will our future data on which we make decisions be accurate? Actually, No and we are already seeing this happen with all the home self-tests already being sold. And then the “sick” patients should self-quarantine, that if they are honest and care about those around them and those who matter to them, or just care about society.
This new variant/mutation is more contagious, and our population is exhausted. If you don’t believe me just review the New Year’s Eve celebration from Nashville or New York city. The crowds were huge and there were very few masks being worn!
Omicron not peaking nationally yet, surgeon general says. COVID-19 is sending mixed messages. The U.S. is recording over 800,000 cases a day for the first time since the beginning of the pandemic, and hospitalizations are also setting records.
But New York State recorded only about 48,000 cases on Friday, almost a 47% drop from the previous week’s case count, Gov. Kathy Hochul said Saturday.
“We are turning the corner on the winter surge, but we’re not through this yet,” the governor said in a statement.
Minnesota also saw declining intensive-care hospitalizations for COVID-19, and cases have been falling in Washington D.C. and other cities in the eastern half of the country.
But New York’s declining trend is not indicative of the national COVID-19 portrait, Surgeon General Vivek Murthy warned on Sunday.
“The entire country is not moving at the same pace,” he told CNN host Jake Tapper.
Oklahoma and Georgia both saw over a 100% rise in weekly COVID-19 cases, a USA TODAY analysis of Johns Hopkins University data shows, while Colorado saw a 90% increase.
“We shouldn’t expect a national peak in the next coming days,” he said. “The next feel weeks will be tough.”
Also in the news:
The United States has reported its 850,000+ deaths, Johns Hopkins University data shows. The U.S. averaged 1,776 reported deaths per day over the last week.
The Biden administration on Wednesday will launch a website where Americans can order up to four free COVID-19 testing kits per person.
U.S. Rep. David Trone of Maryland announced that he has tested positive for COVID-19. Trone said he has received a booster and is experiencing “only minor symptoms,” according to The Washington Post.
Navajo Nation President Jonathan Nez has signed an executive order requiring all government workers on the tribe’s vast reservation to receive a booster shot.
Today’s numbers: The U.S. has recorded more than 65 million confirmed COVID-19 cases and more than 850,000 deaths, according to Johns Hopkins University data. Global totals: More than 326 million cases and over 5.5 million deaths. More than 208 million Americans – 62.9% – are fully vaccinated, according to the Centers for Disease Control and Prevention.
What we’re reading: Omicron is closing daycare centers in droves. Parents are “just trying to stay afloat.” USA TODAY’s Alia Wong explains.
US now averaging 800,000 new cases each day and stated that the total deaths are now over 900,000.
The United States is reporting more than 800,000 cases a day for the first time, even amid signs that America’s omicron wave is slowing down. The country reported 5.65 million cases in the week ending Saturday, a USA TODAY analysis of Johns Hopkins University data shows. The rapid acceleration of case reports continues despite a shortage of tests. Still, in just the last week the country has reported more cases than it did in March, April, May and June 2021 – combined.
About 158,500 Americans were reported hospitalized on Saturday. Hospitals in 46 states report rising numbers of patients; 34 states report rising death rates.
Mike Stucka noted that we continue to push mask mandates, social distancing, vaccinations, and possible additional lockdowns.
With the majority of really sick hospitalized patients, actually about 72%, were non-vaccinated.
I just had a young lady with four children who notified me earlier in the week that because she had a few home self-tests she tested her sons with two of the boys just having sniffles or a minor sore throat. And three tested positive. And I believe that this is going to be the majority of COVID positive patients, that is minimal or no symptoms and therefore, not self-quarantining and therefore becoming super-spreaders.
COVID Vaccines Are a Scientific Feat, but ‘Prevention’ Is a Misnomer
— In public messaging, semantics matter
Rossi A. Hassad, PhD reported that especially since the advent of the COVID-19 Omicron variant, and the increasing incidence of infection and reinfection among those fully vaccinated and boosted, I have heard from a number of people whose concerns reflect the following sentiment, “You recommended the vaccine to prevent COVID-19, I took it, and this is what I got (infected).”
Undoubtedly, these COVID-19 vaccines are a gift of life and continue to be safe and effective. Nonetheless, this sentiment is understandable, and in my assessment, it signals an urgent need for more precise labeling and messaging about the COVID-19 vaccines from the FDA.
On Dec. 10, 2020, at the invitation of the FDA, I gave a brief oral presentation at the open public session of the Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting for emergency use authorization (EUA) of the Pfizer-BioNTech COVID-19 vaccine. I ended my remarks as follows:
“In conclusion, the potential benefits of this vaccine outweigh the identified risks. Therefore, I support the issuance of an EUA with the stipulation that the vaccine can protect against symptomatic disease. But at this time, it is not known if it prevents infection and transmission.”
The COVID-19 vaccine clinical trials and the resulting evidence show that the vaccines significantly reduce the risk of severe illness, hospitalization, and death. Nonetheless, in the labeling of the vaccines, and messaging to healthcare providers and the general public, the FDA specified that the Pfizer-BioNTech, Moderna, and Janssen vaccines are indicated for the “prevention of COVID-19” — this may have fostered an unrealistic expectation of absolute protection or immunity against COVID-19. By scientific convention, a vaccine is generally characterized as a primary prevention measure for a specific disease: that is, “you can be exposed to it without becoming infected.”
Over the summer, on Aug. 2, 2021, I emailed FDA’s Acting Commissioner Janet Woodcock, MD, regarding the word prevention, which the FDA has used to characterize the scope of protection provided by the three COVID-19 vaccines in use in the U.S. I noted that the word prevention in this context seems to be a misnomer and can contribute to public confusion and vaccine hesitancy. In particular, in light of the increasing number of breakthrough cases, the public may be inclined to believe that the COVID-19 vaccines are losing effectiveness. I also urged the FDA to provide clarification to the public in this regard. Woodcock responded the same day as follows:
“Thank you for writing. We will take your suggestions into account. I agree that the expected results of vaccination are confusing for most people. It is very likely that vaccination prevents acquisition of infection in some people but not all vaccinated people and that some get symptomatic infection and rarely, severe disease, and this may be related in part to their overall immune system response, the variant they were exposed to, and the actual amount of exposure and the time since their last vaccination, among other things.”
Notably, in September 2021, the CDC tempered its definition of vaccination to reflect that vaccines produce “protection from a specific disease,” rather than “immunity to a specific disease.” (In either case, immunity was defined on the same CDC page as “protection from an infectious disease.”)
Woodcock’s response continues to reflect the performance of the COVID-19 vaccines. Prevention of COVID-19 is not the intended primary benefit of these vaccines. In fact, Woodcock and Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, recently made the point that most people will get COVID eventually. These vaccines continue to significantly reduce the risk of severe illness, hospitalization, and death — and that’s an amazing scientific feat amidst a deadly pandemic. Attention to timely and effective messaging to healthcare providers and the general public should be a top priority for the FDA. Semantics matter.
(When) to Boost or Not to Boost, That Is the Question
— Countless complex questions remain
John P. Moore, PhD noted that for several months, America has been in the vaccine-booster phase of the COVID-19 pandemic. Various aspects of booster policy have been controversial and/or confusing, and the public response to the need for boosters has been mixed. But what is the best way to continue to provide the sensible majority who trust in the lifesaving COVID-19 vaccines with the best protection in the coming months to years? At times, it seems as if some folks believe “a dose a day keeps the doctor away.” And a meme is now circulating of a “Pfizer Loyalty Card,” offering a free pizza after dose nine. While droll, might that actually happen? (Dose nine, that is).
While the strong protective efficacy of the mRNA vaccines was certainly not predicted early on in the global vaccine program, a basic understanding of vaccine immunology allowed us to predict that protective antibody titers would inevitably wane over a 6-month period and could be restored with a booster dose.
The Early Booster Debates
In summer 2021, data from Israel triggered discussions among policymakers, scientists, and company executives about the need for boosters in the U.S. The vaccine booster concept wasn’t — or shouldn’t have been — inherently controversial, particularly for individuals at high risk for COVID-19 complications. However, there were doubts about the arguably premature timing of, and rationale for, a broadly based boosting program. Arguments were also raised about using those doses in under-vaccinated countries instead, both on moral grounds and to prevent the emergence of even more troubling variants (e.g., Omicron…). Other debates centered on whether the goal was to protect against mild infections (which vaccines typically don’t do) or severe disease and death. These discussions generally faded away once it became clear that protection against severe infections was diminishing significantly for older individuals, and that fully vaccinated people could still transmit their infections to others. In addition, anxious members of the vaccine-embracing public, including members of the media, put pressure on the Biden administration. A vaccine boost became something that Jane Public and Ronnie Reporter wanted, and, frankly, expected.
Americans can now be boosted 5 months after their initial two mRNA vaccine doses of Moderna or Pfizer. The far fewer recipients of the Johnson & Johnson (J&J) vaccine are also being boosted, most opting for an mRNA dose as that provides a stronger antibody response.
But what’s next? Already, Israel is rolling out a fourth Pfizer dose and is therefore well on the way to handing over a slice of pizza. Should we do the same here, and if so, when? In the hope that any policy decisions will be science-based, I will review some of the knowns and unknowns. Whatever knowledge I possess has been significantly boosted by helpful discussions with world-class immunologist colleagues.
Determining the Right Booster Schedule
Most agree that dose three (i.e., the first boost) should not be given too early. The period between the second and third dose is critical to the maturation of the immune response and establishment of immunological memory. As the quantity of antibodies in the blood declines, their quality increases, including their ability to counter variants. While there is no “magic moment” for dose three, the original CDC recommendation for a 6-month gap for both mRNA vaccines and the recent revisions to 5 months are both about right.
But what about dose four and onwards? Is there a point when it is certainly needed? Here, we don’t have hard data, although there are early indications from Israel that the antibody responses to Pfizer dose three are now dropping. That should not be a surprise, based in part on decades of experience with attempts at an HIV-1 vaccine. As but one illustrative example, an HIV-1 “spike protein” vaccine was given seven times to humans over a 30-month period. After the first two immunizations, every subsequent one triggered a rapid rise in antibody levels, followed by a gradual decline at a similar rate each time. The titer pattern over time looked like saw teeth. In the period between boosts, the antibody levels didn’t disappear, but the boosted peak levels weren’t much higher each time — there were ever diminishing returns to the potency of each booster dose.
Perhaps we will see something different with the SARS-CoV-2 spike protein, and maybe the mRNA delivery method will be the charm — but I wouldn’t bet the farm on a dramatically different outcome to our experiences with the HIV-1 spike protein. In other words, boosting is likely to increase protective antibody levels in the short term but probably won’t be truly sustained (T-cell responses, which help to prevent severe disease, also wane but more slowly). If the pandemic persists, fairly regular boosting may therefore be needed, akin to the annual flu vaccines.
However, this scenario also invites more questions about the intervals between doses: the HIV-1 vaccine study discussed above used a 6-month interval between the later doses, probably because prior experience showed that was when the boosted titers dropped back to near baseline. The Israelis, however, are now giving the fourth Pfizer vaccine dose about 4 months after the third. Is that too soon for comfort? Well, for sure, it should be no sooner than that…and most immunologists I talked to favor a longer interval. Given the cost and logistics, some important decisions will need to be made soon.
Our political and public health leaders have much to consider and will need to decide whether there is a need to sustain a high level of protection against SARS-CoV-2 infection and mild COVID-19.
Will We Keep Boosting…Forever?
What about the future? There is nothing inherently problematic with giving regular, sensibly spaced vaccine doses from an immunology perspective. Different COVID-19 vaccines can clearly be mixed when given sequentially. A recent HIV-1 vaccine study in monkeys involved nine doses of mRNAs, proteins, and protein-nanoparticles over a ~14-month period in a heroic attempt to broaden the neutralizing antibody response (the major obstacle to a successful HIV-1 vaccine). Next-generation, more potent COVID-19 vaccines may eventually play an important role. We’ll also need to explore alternative ways to deliver vaccines, whether based on immunology or emerging technology. What happens should be dictated by the trajectory of the pandemic, including the evolution of yet more variants. So far, despite vaccine manufacturers going ahead with their own plans, the case for variant-specific vaccines has been weak. Although, it’s possible the need for them may change in the coming months as Omicron continues to spread; and now what about the new variant, Deltacron?
Boosting J&J Vaccine Recipients
Additional complications are at play too: What’s the right approach to boosting J&J vaccine recipients? They can receive a second dose 2 months after the first, but in most cases that dosing interval is many months longer (and, as noted, most opted for an mRNA boost at that point). When should they receive a third dose? For the mRNA vaccines, the critical period for immunological quality improvements is the ~6-month interval between doses two and three (see above), but when does that happen for the J&J vaccine? In the long and rather random interval between doses one and two? After dose two? Or both? Could a third dose in the near future be too soon for comfort? Having more data would help.
Factoring in Natural Immunity
We also need to consider how to — or whether to — factor in immune responses induced by vaccine breakthrough infections, which are becoming increasingly common. Although breakthrough Omicron infections are generally not severe, the viral antigens will surely trigger a boosting effect in vaccine-primed immune systems — some members of the public are now embracing this idea. And we know that vaccinating previously infected people generates particularly strong immune responses (“hybrid immunity”). We can expect a lot of data on this topic in the next month or so, but for now we have to speculate.
But what happens when vaccination precedes infection? Should a two-dose vaccine recipient who is then Omicron-infected receive a further vaccine dose and, if so, when? Similarly, what happens if a triply vaccinated person becomes infected? Given how mutated the Omicron spike-protein is, an infection with this variant is likely to trigger the production of antibodies that have a lesser impact on new variants that more closely resemble the ones that circulated in 2020-2021. They would, however, be better poised to counter any variants that emerge from the Omicron lineage, as would Omicron-based vaccine boosters. In short, we need to determine how to factor in the combination of vaccination and infection history, and also how the pandemic may further evolve, to devise an optimal boosting approach. There are important scenarios that policymakers and serious immunologists must ponder soon. Otherwise, far-reaching decisions will be taken on the fly, which is never ideal.
The U.S. is blessed with an abundance of COVID-19 vaccines and world-class scientists. Our complex scenarios merit the most qualified experts to figure out the best paths forward. I, for one, look forward to reading what might emerge. I need that guidance to answer with greater confidence the questions I am frequently asked by friends, colleagues, and random members of the public. “Winging it” is becoming as tiresome as it is tiring.
Now that we have two antiviral medications that can be taken after a patient gets infected, I predict that all will change and that by the middle of February the pandemic will be declared over and be classified as an endemic. That will mean that we will be” instructed” to simply get our “up-dated shots” yearly with our updated flu vaccinations.
Infact, Moderna is already working on a combined vaccine to include updated influenza and COVID vaccines, which would be “offered” yearly.
So, can we get back to normal? Maybe! We still have to continue to assess the use of vaccines to those under the age of 5 years old. Once we have critically evaluated and cleared vaccines and antiviral medications for these young potential patients, we will have a safer healthcare system to “return to normal”.
As nations decide to live with the virus, some disease experts warn of surrendering too soon. The coronavirus isn’t going away, but that doesn’t mean resistance is futile, scientists say.
Joel Achenbach wrote that Nations around the planet are making a subtle but consequential pivot in their war against the coronavirus: Crushing the virus is no longer the strategy. Many countries are just hoping for a draw.
It’s a strategic retreat, signaled in overt and subtle ways from Washington to Madrid to Pretoria, South Africa, to Canberra, Australia. Notably, few countries today outside of China — which is still locking down cities — cling to a “zero-covid” strategy.
The phrase often heard now in the United States and many other nations is “live with the virus.” That new stance is applauded by some officials and scientists and welcomed by people exhausted with the hardships and disruptions of this global health emergency entering its third year.
But there are also disease experts who fear the pendulum will swing too far the other way. They worry that many world leaders are gambling on a relatively benign outcome from this omicron variant surge and sending messages that will lead people who are normally prudent to abandon the social distancing and mask-wearing known to limit the pathogen’s spread. Epidemiologists say the live-with-it strategy underestimates the dangers posed by omicron.
“This notion of learning to live with it, to me, has always meant a surrendering, a giving up,” World Health Organization epidemiologist Maria Van Kerkhove said.
Virologist Angela Rasmussen of the University of Saskatchewan likewise fears that people are relaxing sensible precautions prematurely: “I understand the temptation to say, ‘I give up, it’s too much.’ Two years is a lot. Everybody’s sick of it. I hate this. But it doesn’t mean actually the game is lost.”
The WHO officially declared a public health emergency of international concern on Jan. 30, 2020, when there were 7,711 confirmed cases of covid-19 and 170 deaths in China, and another 83 cases scattered across 18 other countries — and no deaths.
Two years later, the virus has killed more than 5.5 million people, and the pandemic is ongoing. But the global health emergency has evolved — reshaped by the tools deployed to combat it, including vaccines. The virus itself and the disease it causes are now so familiar, they have lost some of their early spookiness.
No national leader would ever say that it’s time to quit the struggle, but the tone of the contest has changed, with little talk of beating, crushing, defeating the virus. SARS-CoV-2 is part of the world now, a “pantropic” virus that can infect people, deer, minks, rats and all sorts of mammals.
Many nations continue to impose mask requirements, vaccination mandates and travel restrictions. But few leaders in democratic societies have the political capital to take harsh measures to suppress transmission. Even the arrival of the ultra-transmissible omicron variant did not throw the world back into winter 2021, when the paramount goal remained stopping viral spread at all costs — much less back to spring 2020, when people were told to stay home, wipe down their groceries and not touch their face.
Even officials in Australia, long a fortress nation that sought to suppress the virus at all costs, have chosen to ease some mandates in recent weeks.

The country has gained global headlines for its treatment of unvaccinated tennis champion Novak Djokovic, who flew in for the Australian Open and immediately ran afoul of the government’s virus protocols, spending the better part of a week in a detention hotel. On Friday, Australia’s immigration minister canceled the player’s visa a second time.
But the other national story in Australia is a debate over the relaxed restrictions. National and state leaders had an agreement that strict measures would end when vaccination reached 80 percent of the eligible population. That threshold was reached months ago, and now more than 90 percent of the eligible population is vaccinated. Masks are still required in some indoor settings, and there are capacity limits, but opposition leaders and some experts have decried what they call the “let it rip” strategy.
“The decision to remove restrictions just as Omicron surged has cost us dearly,” declared a report from an independent group of experts called OzSAGE. “The ‘let it rip’ strategy and defeatist narrative that ‘we are all going to get it’ ignores the stark lived reality of the vulnerable of our society.”
In South Africa, where officials first sounded the alarm about omicron, the government in December eased protocols, betting that previous encounters with the virus have given the population enough immunity to prevent significant levels of severe illness. The omicron wave there subsided quickly with modest hospitalizations, and scientists think one reason is that so many people — close to 80 percent — had previously been infected by earlier variants.
Omicron also appears to be less virulent — less likely to cause disease. This heavily mutated coronavirus variant stiff-arms the front-line defense of antibodies generated by vaccines and previous infection but does not seem to be adept at invading the lungs or escaping the deeper defenses of the immune system.
In the ideal scenario, omicron’s alarming wave of infections will spike quickly, leaving behind a residue of immunity that will keep a broad swath of the population less vulnerable to future infections. This would be the last major, globally disruptive wave of the pandemic. The virus would still be around but would no longer be in a special category apart from other routinely circulating and typically nonfatal viruses such as influenza.
There are other scenarios less attractive. Scientists are quick to point out that they don’t know how long omicron-induced immunity lasts. The virus keeps mutating. Slippery variants packing a more powerful punch could yet emerge, and virologists say that contrary to what has sometimes been conjectured, viruses do not inexorably evolve toward milder strains.
But humans change, too. Outside of locked-down China, most people are no longer immunologically naive to the coronavirus. Scientists believe that’s a factor in omicron’s relatively low severity for individual patients. In the long term, humans and viruses tend to reach something like a stalemate. Only one disease-causing virus, smallpox, has ever been eradicated.
In the short term, experts believe omicron is essentially unstoppable but of limited threat to individuals even as it causes societal chaos. Ali Mokdad, an epidemiologist at the University of Washington’s Institute for Health Metrics and Evaluation, said he believes that about half of the U.S. population will be infected with omicron during the next three months, with most cases asymptomatic.
“There’s no way to stop its spread — unless we do measures like China is doing, and you and I know very well that’s not possible in the United States,” Mokdad said.
‘New normal’
There is no unified global response to the pandemic. Despite calls to “follow the science,” scientific research cannot dictate the best policy for some of the stickiest issues — such as when to open schools to in-person learning, or who should be prioritized for vaccines, or whether people who have no symptoms should be regularly tested.
The national strategies typically reflect elements of a country’s culture, wealth, government structure, demographics and underlying health conditions. Also, geography: New Zealand has managed to record only a few dozen deaths from covid-19, one of the lowest per capita death tolls on the planet, by leveraging its isolation in the South Pacific.
Japan, Singapore and South Korea, nations with a long history of mask-wearing and aggressive measures to suppress epidemics, have managed to keep the virus largely in check without draconian lockdowns or major sacrifices to their economies.
Peru, hammered by the variants dubbed lambda and gamma before the delta and omicron waves arrived, has had the deadliest pandemic per capita, according to the Johns Hopkins University coronavirus tracking site. The nations of Eastern Europe, with older populations and high vaccine skepticism, are not far behind.
Countries have different and sometimes unreliable ways of documenting the pandemic, but some general trends are clear. Among the wealthiest nations, the United States — where the pandemic is thoroughly polarized, misinformation is rampant, and a significant fraction of the public has resisted vaccination — has had an unusually deadly pandemic. According to the Hopkins tracker, the United States ranks 21st in reported deaths per capita. Britain is not much better at 28th, while Canada is 82nd.
A group of doctors who advised President Biden during the presidential transition have urged a reset of the strategy to recognize the “new normal” of the virus, which has little chance of being eradicated and will probably continue to cause typically mild illness and require vaccination boosters at a frequency yet to be determined.
Biden took office nearly a year ago vowing to crush the pandemic, having won the presidency in part by emphasizing a more aggressive posture against the contagion than President Donald Trump. Biden’s administration pushed vaccination hard and saw millions of people a day roll up their sleeves during the spring. On July 4, after caseloads had dropped, he assembled a crowd on the South Lawn for a celebration of independence from the virus.
But the surge of infections and deaths from the delta variant proved that celebration to be premature, and the Centers for Disease Control and Prevention revised its guidelines, saying even those people fully vaccinated should resume wearing masks indoors. The delta wave began to subside in the fall, but then omicron, crammed with mutations that make it wildly more transmissible and evasive of immunity, erupted in late November.
Biden’s omicron strategy is not significantly different from what he employed against previous variants. On Dec. 2, he detailed his plans by first announcing what he would not do: “lockdowns.” He vowed to distribute 500 million rapid tests and doubled the number in recent days. His covid task force continues to emphasize the importance of vaccines, therapeutics and testing rather than restrictions on mobility and gatherings.
Fatalism and fatigue
The strategic shift toward the live-with-it strategy in many nations, including the United States, has often gone without formal acknowledgment from national leaders. Spain is one of the exceptions: Prime Minister Pedro Sánchez has said he wants the European Union to stop tracking covid as a separate disease and recognize that it is becoming an endemic pathogen.
Across the Pyrenees, French nightclubs closed as omicron swept through. Indoor masking is required, regardless of vaccination status. In bars, patrons are not allowed to consume alcohol while standing up. France, like Italy and many other European countries, has leaned heavily on vaccine passports.
French President Emmanuel Macron is blunt about his desire to make life uncomfortable for the unvaccinated by limiting their ability to go into public places. In a newspaper interview, he used graphic language that has been translated into English as “I really want to piss them off.”
Many global leaders, including those in the United States and Europe, have focused on vaccination as the key to mitigating the pandemic. The vaccines do lower the risk of severe illness. What they do not do as well is stop transmission and mild infection. The speed of omicron’s spread is the key factor in the equation that determines how much pressure it will put on hospitals — which are currently seeing record numbers of covid patients in the United States.
“If we just completely let everything go and allow the omicron epidemic to run its natural course, we’ll completely overrun our health system and be left in a situation potentially worse than what we experienced in early 2020,” said James Lawler, co-director of the University of Nebraska Medical Center’s Global Center for Health Security.
He is not seeing the precautions he saw early in the pandemic, when he was among the first disease experts to sound an alarm about the extreme transmissibility of the coronavirus. Earlier this week, he went to a grocery store and was virtually alone in wearing a mask. That’s the norm, he said, in Omaha.
“There’s not a mandate,” he said. “Across the entire experience of humanity, we should have learned by now the only way to get high levels of compliance like this is to make it mandatory. That’s what happened with seat belts.”
After Lawler made those comments, a county health commissioner imposed a mask mandate covering Omaha, but the Nebraska Attorney General filed a lawsuit to block it.
There is fatalism mixing with pandemic fatigue and, in some countries, science denial or ideological rejection of the restrictions and mandates that many public health experts consider to be common sense measures in a pandemic. And anecdotally, people may rationally feel the battle is lost, the virus has won.
Public health officials warn that this is a dangerous attitude. It’s true that for an individual, risk might be low. But when a virus spreads as quickly as omicron does, the equation suddenly spits out alarming results — millions of people sick at once, many of them with underlying conditions that have already put them on the edge of a cliff and vulnerable to a shove.
Rasmussen, the University of Saskatchewan virologist, is among the experts who think people have misunderstood the concept of endemicity — which is the point at which a virus continues to circulate at low levels but is not generating epidemic-level outbreaks. She fears some people hear the “endemic virus” talk as a sign that resistance is futile.
“People think that means we just give up,” she said. “They think ‘endemic’ means that we’re all going to get covid eventually. I’m hearing people say, ‘Why not just get it over with now, and I’ll be bulletproof?’ None of this is what endemicity means.”
Endemic COVID doesn’t mean it’s harmless or we give up, just that it’s part of life
Catherine Bennett discusses the eventual change in her article. We have experienced many bumps in the road since 2020 and one would have to be extremely brave to predict what the pandemic may throw at us next.
But in terms of the endgame, many experts believe COVID will eventually become an endemic disease. However, what this actually means is a source of considerable confusion. One of the main reasons for this is a misunderstanding of endemicity itself, and what COVID being an endemic disease would actually look like in the real world.
Let’s break it down. What does ‘epidemic’ actually mean? A disease is either epidemic or endemic. The most straightforward explanation of an epidemic disease is that it’s one in which the number of cases in the community is unusually large or unexpected. When this occurs, it signals a need for public health action to bring disease transmission under control.
In the case of a pandemic—a worldwide epidemic—this occurs on a much larger scale. Depending on the infectiousness and severity of the disease, it can represent a global public health emergency, as we’ve seen with COVID.
When you have the emergence of a completely new virus like SARS-CoV-2 that has the potential to cause severe illness while also being highly transmissible, the lack of any immunity among the population results in the drivers for disease spread being incredibly strong.
A disease being epidemic indicates there’s an imbalance between these drivers of disease spread and the factors limiting spread in the community. In short, it means the drivers for disease spread overpower the factors limiting spread. As such, the disease spreads like a raging bushfire. It’s explosive and hard to bring under control once it has seeded.
From epidemic to endemic
However, over time, the underlying forces driving an epidemic alter. As immunity begins to increase across the population—ideally in a controlled way by vaccination, but also by natural infection—the pathogen starts to run out of fuel and its ability to transmit falls. Pathogens can include a variety of microorganisms, such as viruses, bacteria and parasites. In this case, let’s assume we’re talking about a virus.
On top of immunity, we can also reduce a virus’ ability to spread by behavior changes, such as 1 / 3 limiting contact with others, mask wearing and improved hand hygiene. In addition to lowering the virus’ ability to transmit, immunity also reduces its ability to cause disease, meaning fewer people become really sick or die.
And finally, if we are lucky, over longer periods of time, the virus may also evolve to become intrinsically less severe. When will the COVID-19 pandemic end?
The net result of this is we move from an imbalance in terms of the forces driving disease to a steadier state of equilibrium. Instead of explosive and unpredictable disease spread, we reach a point where the presence of circulating disease represents a lower threat to the community than it did at the beginning of an epidemic.
Transmission becomes more predictable, but not necessarily constant—we may still see some waves, especially seasonally. But these are expected and manageable. In short, we start to live alongside the virus.
This is what we mean by an endemic disease. Examples of endemic diseases include the common cold, influenza and HIV/AIDS. Endemic doesn’t mean we drop our guard. The discussion around COVID becoming endemic becomes even more complicated by very different views about what this actually translates to in practice.
It’s important to emphasize it doesn’t mean we drop our guard, surrender to the virus or downgrade the threat the virus poses to individuals and the community. We remain vigilant and respond to surges in cases when they occur, doing what’s needed to keep transmission as low as possible.
Importantly, a disease being considered endemic doesn’t mean we consider it mild. It just means it remains a part of our lives, and therefore we still protect the vulnerable from severe illness, as we do with other diseases. It’s crucial we understand living with the virus isn’t the same thing as ignoring the virus. Instead, it represents an adjustment in the way in which we respond to the disease.
It’ll be a bumpy ride. It’s also important to highlight this transition may not necessarily be smooth and there will no doubt be challenges along the way. One of the main obstacles we’re going to face is the possible emergence of new variants and how these will impact the infectiousness and severity of the disease.
In order to reduce the likelihood of new variants emerging, it’s vital we really step up our rollout of vaccines globally to reduce virus transmission. To aid us in our transition to this next stage of the pandemic, we will, thankfully, be able to draw on many new weapons which are in the pipeline. This includes next-generation vaccines which will be more effective against the latest variants, or universal vaccines that cover all variants. We expect new vaccines will also be better at controlling transmission.
We’ll also have ever-improving treatments, and better infection prevention and control engineered for specific environments. The big question, of course is when will this transition to endemicity happen? Many experts, 2 / 3 believe huge strides will be made along this path in 2022.
It has been reported by the WHO that Omicron sub-variant has been found in 57 countries. A sub-variant of the highly contagious Omicron coronavirus strain, which some studies indicate could be even more infectious than the original version, has been detected in 57 countries, the WHO said Tuesday.
The fast-spreading and heavily mutated Omicron variant has rapidly become the dominant variant worldwide since it was first detected in southern Africa 10 weeks ago. In its weekly epidemiological update, the World Health Organization said that the variant, which accounts for over 93 percent of all coronavirus specimens collected in the past month, counts several sub-lineages: BA.1, BA.1.1, BA.2 and BA.3.
The BA.1 and BA.1.1—the first versions identified—still account for over 96 percent of all the Omicron sequences uploaded to the GISAID global science initiative, it said. But there has been a clear rise in cases involving BA.2, which counts several different mutations from the original including on the spike protein that dots the virus’s surface and is key to entering human cells.
“BA.2- designated sequences have been submitted to GISAID from 57 countries to date,” The WHO said, adding that in some countries, the sub-variant now accounted for over half of all Omicron sequences gathered. The UN health agency said little was known yet about the differences between the sub-variants, and called for studies into its characteristics, including its transmissibility, how good it is at dodging immune protections and its virulence. Several recent studies have hinted that BA.2 is more infectious than the original Omicron.
Maria Van Kerkhove, one of the WHO’s top experts on COVID, told reporters Tuesday that information about the sub-variant was very limited, but that some inital data indicated BA.2 had “a slight increase in growth rate over BA.1”
Omicron in general is known to cause less severe disease than previous coronavirus variants that have wreaked havoc, like Delta, and Van Kerkhove said there so far was “no indication that there is a change in severity” in the BA.2 sub-variant. She stressed though that regardless of the strain, COVID remained a dangerous disease and people should strive to avoid catching it. “We need people to be aware that this virus is continuing to circulate and its continuing to evolve,” she said. “It’s really important that we take measures to reduce our exposure to this virus, whichever variant is circulating.”
Merck to Deliver 3.1 million Treatment Courses of COVID Antiviral
Ralph Ellis reported that a little more than a month after receiving FDA authorization, Merck has delivered 1.4 million courses of its COVID-19 antiviral pill in the United States and expects to deliver its total commitment of 3.1 million treatment courses soon, company CEO Rob Davis said on CNBC.
Merck has also shipped 4 million courses of the pill, molnupiravir, to 25 nations across the world, he said. “We’ve shown that molnupiravir works against Omicron, which is important against that variant,” Davis said Thursday morning. “And obviously we’ll have to see how this plays out and what is the initial uptake, but right now we feel we’re off to a good start.”
In June the U.S. government agreed to buy 1.7 million courses of molnupiravir for $1.2 billion and in November agreed to buy an additional 1.4 billion courses for $1 billion.
The FDA granted emergency use authorization in late December to two antivirals for people who contract COVID: Merck’s molnupiravir and Paxlovid, which is produced by Pfizer. The drugs are designed for people with mild or moderate COVID who are more likely to become seriously ill — mainly people 65 and older or people who have chronic illnesses such as heart disease, lung disease, diabetes, obesity, or compromised immune systems.
Both antivirals require a five-day course of treatment. Merck’s is for adults ages 18 and older, and Pfizer’s for anyone age 12 and up. In clinical trials, molnupiravir reduced the risk of hospitalization or death in Covid patients by 30% but slashed the risk of dying by 90%, Davis said.
“The fact that molnupiravir does reduce the risk of death by 90%, we could have a meaningful impact in helping patients,” he said. Davis told CNBC that Merck sold $952 million in molnupiravir pills in the fourth quarter and is on track to rack up an extra $5 billion to $6 billion in sales in 2022.
Last week, Merck said laboratory studies showed molnupiravir was active against the Omicron variant. In December, Pfizer said preliminary lab studies also suggest the pill will hold up against the Omicron variant.
WHO official sees ‘plausible endgame’ to pandemic; Medicare to provide up to 8 free tests per month: COVID updates
John Bacon,Jorge L. Ortiz and Celina Tebor wrote in USA Today that the director of the World Health Organization’s Europe office said Thursday that coronavirus deaths are starting to plateau, and the continent faces a “plausible endgame” to the pandemic.
Dr. Hans Kluge said there is a “singular opportunity” for countries across Europe to take control of COVID-19 transmission as a result of three factors: high levels of immunization because of vaccination and natural infection, the virus’s tendency to spread less in warmer weather and the lower severity of the omicron variant. Data in the U.S. is similar to the data from Europe, providing similar hope.
“This period of higher protection should be seen as a cease-fire that could bring us enduring peace,” Kluge said.
At WHO’s Geneva headquarters, director-general Tedros Adhanom Ghebreyesus warned that the world as a whole is far from exiting the pandemic.
“We are concerned that a narrative has taken hold in some countries that because of vaccines, and because of omicron’s high transmissibility and lower severity, preventing transmission is no longer possible and no longer necessary,” Tedros said. “Nothing could be further from the truth.”
So, with the announcement that Pfizer has submitted their studies on 6 months to 5-year vaccine approval, the antivirals and the vaccine statistics, that the change to COVID-19 to be transitioned to the classification as an Endemic is right around the corner.
And lastly-
US Exiting ‘Full-Blown Pandemic Phase’ of COVID, Fauci Says
Carolyn Crist wrote the latest prediction from Dr. Fauci. The U.S. is heading in a positive direction in the pandemic as COVID-19 cases and hospitalizations decline, said Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases.
Vaccination rates, treatments, and prior infections will make the coronavirus more manageable in 2022, Fauci told the Financial Times. Broad mandates and mitigation protocols will begin to be lifted.
“As we get out of the full-blown pandemic phase of COVID-19, which we are certainly heading out of, these decisions will increasingly be made on a local level rather than centrally decided or mandated,” he told the newspaper. “There will also be more people making their own decisions on how they want to deal with the virus.”
The U.S. is reporting an average of 240,000 new COVID-19 cases per day, according to the data tracker from The New York Times. That’s a 63% decline from the previous 2 weeks.
About 100,000 people are hospitalized due to COVID-19, according to the latest data from the U.S. Department of Health and Human Services. That’s also down 28% in the past 2 weeks.
At the same time, about 2,600 deaths are being reported each day, the newspaper reported, which is the highest level seen in the U.S. in a year.
Fauci said COVID-19 restrictions around the U.S. will end soon. He didn’t give a specific timeline but said it was likely to happen in 2022.
Some states have already begun to lift pandemic rules as COVID-19 cases subside. California, Connecticut, Delaware, Oregon, and New Jersey announced on Monday that they would lift mask mandates for schools and other public spaces throughout February and March. On Wednesday, New York Gov. Kathy Hochul dropped New York’s mask mandate as well.
At the same time, Fauci stressed that the coronavirus won’t be wiped out and people will have to learn to live with it. Health officials may soon reach an “equilibrium” where they don’t need to monitor infection levels as closely, he said.
“I hope we are looking at a time when we have enough people vaccinated and enough people with protection from previous infection that the COVID restrictions will soon be a thing of the past,” he said.
And I believe that we are just about there!

Throw Away Your Mask After COVID Vaccination or Not, What about the Mutations and Infection after Vaccination?

As our national mortality statistics reach over 500,000 and a third vaccine has been approved by the FDA I thought that we should examine the use of masks, etc. after vaccinations. This is an important question especially considering the increasing findings of more viral mutants.

 Recently, a spirited discussion was sparked on social media: is it acceptable to relax masking 14 days after the second COVID-19 vaccine dose? Doctor Vinay Prasad and Doctor David Aronoff, in this post will discuss the advice as to whether to continue wearing masks as well as social distancing, etc. after one completes their vaccination.

Doctor Prasad starts off by noting that having spent some time thinking about the topic, and discussing with colleagues, I have reached two conclusions. First, it is a tradeoff with residual uncertainties, and reasonable people can disagree. But also, I favor the view that generally, 14 days after vaccination, we can relax some restrictions.

The caveats

It is important to be upfront with the caveats. Everything I say applies to average people in the community — I am not speaking about enhanced precautions in high-risk settings like nursing homes or medical centers. My argument is contingent on there being no “vaccine escape,” that is, no mutation in the coronavirus that markedly reduces vaccine efficacy. If that happens, may God help us. I am not sure we will make it.

Finally, my argument is appropriate for most places and most times, but if health systems are overwhelmed, e.g., as we saw in places like southern California or New York City, it might be reasonable to temporarily increase precautions. Additionally, my guiding principle does not apply to businesses, such as grocery stores or pharmacies, which can and will enforce their own policies.

Now, having said that: for most people, once you get 14 days out of your second dose of vaccine, I believe you can ease up on masking or another restriction, such as visiting a loved one for lunch or having more than one person visit a nursing home at the same time, or a small gathering of vaccinated people for dinner without masks.

The data

There are three lines of evidence that I wish to offer for my claim. First, consider the efficacy of the vaccine. The efficacy of the two mRNA vaccines is superb, offering 95% reduction in the rate of acquisition of symptomatic COVID-19 in randomized trials. That is a remarkable result. But the key statistic here is one step beyond the vaccine efficacy. If you get two doses of the vaccine, and if you remain asymptomatic 14 days after the second dose, what is the probability you will develop COVID-19? For Moderna, the answer is there is a 99.92% chance that you won’t. Only 12 cases occurred after this time in 14,550 actively vaccinated people in the trial, while the control arm experienced nearly 3.5% cumulative incidence. For Pfizer, only eight cases occurred amongst people who had completed a second dose and went 7 days without symptoms, again a 99.95% chance of not getting COVID if one remained asymptomatic a week after the second dose. In other words, if you get 14 days past the second dose, and feel fine, the likelihood you will get COVID-19 in these studies is very low. Some argue that in the real world — where folks are not as motivated as trial participants — the rate of SARS-CoV-2 acquisition might be higher, and thus relaxing rules riskier. But this logic cuts both ways: if people in the real world are less compliant, then the rules might be relaxed no matter what we say.

Next, consider the risk of spreading SARS-CoV-2 to others. That risk is in part driven by symptomatic infections which are exceedingly rare after second doses. Risk of spreading is diminished by the brisk immune response that occurs after symptomatic infection once someone is vaccinated. In the Moderna study, there were 30 cases of severe COVID overall and zero in the vaccination arm. Less symptomatic and less severe COVID will result in a lower propensity to propagate SARS-CoV-2. Moreover, studies of both recombinant antibody products speed viral clearance from airways. If the body is primed to manufacture anti-spike antibodies through vaccination, there is likely a similar rapid clearance and subsequent reduction in infectiousness occurs.

What about asymptomatic infection and so-called silent spread? In the Moderna trial, swabs taken from asymptomatic participants as they were receiving dose 2 showed a roughly 60% reduction in PCR positivity. It is likely that a second dose and longer asymptomatic period will result in greater reduction in PCR positivity. Preliminary data from AstraZeneca’s ChAdOx1 vaccine also showed reduced in asymptomatic PCR detection. In short, it is highly likely that receipt of vaccination and a 14-day asymptomatic period afterward results in both personal protection and reduced likelihood of ongoing viral propagation.

Third, what is the effect size of masks? More correctly — what is the effect size of masks 14 days after a vaccine with 95% efficacy? What is the effect of masks if PCR positivity is only 1 in 1,000 amongst asymptomatic people? I think we must confront a forgotten truth. Masks make sense not because we have perfect randomized controlled trial data showing they protect the wearer, or others, but based on bio-plausibility, and the precautionary principle, they were a reasonable public health measure to incorporate.

Authors of a 2020 update to the Cochrane review wrote, “Compared to no masks there was no reduction of influenza-like illness (ILI) cases (risk ratio 0.93, 95% CI 0.83-1.05) or influenza (risk ratio 0.84, 95% CI 0.61-1.17) for masks in the general population, nor in healthcare workers (risk ratio 0.37, 95% CI 0.05-2.50).” But the truth is none of these trials perfectly fits the moment. And we never did a cluster RCT of cloth masks — as they are used in the politically torn U.S. — to clarify the effect size with SARS-CoV-2.

The truth is I wear a cloth mask and I quite like it. But I have seen no data that can tell me the added benefit of masks 14 days after vaccination with 95% efficacy. It’s the biological equivalent of asking what happened before the Big Bang. If you ask, what is the evidence that it’s safe to stop wearing a mask, I say, what is the evidence that it’s still beneficial?

This same line of thinking applies to other restrictions that could be eased instead. What evidence supports restricting nursing home visitors, if all parties are vaccinated and masked? What evidence supports banning a small dinner, if everyone has had the vaccine? There is no evidence that supports these continued prohibitions.

Knowing these three facts allows us to put it all together. Is it reasonable to tell someone that, if they are asymptomatic 14 days after the second vaccine, they are highly unlikely to get COVID-19, and also less likely to spread the virus — both by having less severe disease, less asymptomatic carriage, clearing virus faster, stronger antibody responses, and fewer symptomatic cases? Absolutely, is my view.

It is then reasonable to say that the theoretical benefit of the mask may be so small that easing up on its use is fine. Alternatively, you might keep the mask, but ease up on something else, and, to be honest, most people might actually prefer a different concession. You might choose to see family instead, or have a gathering with your vaccinated friends. Getting vaccinated is like getting a stack of tickets at Chuck E. Cheese — you get to decide what to trade them in for!

The politics/sociology

Some contend my stance will undermine efforts to normalize masks, send mixed messages to the public. That’s possible, but it is also possible that my message empowers and excites people to get vaccinated, which is the only viable path out of the nightmare we find ourselves in. I think the less scientists manipulate their statements while trying to guess the response the better. I have tried to be fully transparent in my thinking on this topic. None of us knows the second or third order effects. If we distort the facts and bang on harder about prolonged mask use or other restrictions, will the world actually be better? Or will we provoke a deep backlash that has been brewing for some time? Do we risk losing some folks who might otherwise get vaccinated? I am not an incarnation of God, so I don’t know. I worry that the likes and retweets on social media encourage the fearful message rather than the correct one.

Public health experts have reminded me to talk about despair. We are all facing it, and when you clamp down on a society with restrictions, a free society can only bear it for so long. There must be a path out of it, and easing restrictions — particularly when the burden may outweigh the unproven, theoretical, and at best highly marginal benefit — is a great way to renew optimism. Folks who spend time doing boots on the ground public health share their view with me that this is a great place to start.

The last objection I want to discuss is that my policy is not the safest policy. It is not absolute safety. Indeed, I acknowledge this is true. But I disagree that wearing a mask is absolute safety. I disagree that only one nursing home visitor is the safest policy, and only having a picnic outside is safest. Only truly becoming a hermit is absolute safety. Lock yourself in home, and get all foodstuffs delivered. When you go out, always wear an N95, and do this even a year or two after vaccination. After all, who knows if the vaccine will wear off? None of us really wants absolute safety. We seek reasonable safety, and I will defend the proposition that is achieved merely by a prolonged asymptomatic period after second vaccination and after that something can be relaxed — and there are several options.

The end of COVID

COVID-19 will someday no longer be the topic of daily and breathless news coverage. The virus may always circulate, and some people may always get sick, but the real end will be when we stop thinking about it every moment of every day. That’s how this pandemic will end. Not with a bang, but a whimper.

People need to know that there is light at the end of the tunnel because there is.

Vaccination in the absence of viral escape is the way out of this. Once a person is a sufficient time and distance away from the second shot, and if they are feeling well, we can start to view them differently. They are less a vector for the transmission of a plague, and more a real person — with hopes and wants and desires and seeking connection. In such a moment, if they remove their mask to share a smile with me, I can promise you, I will lower my mask, and smile back.

And Opposing View-Now Is Not the Time to Relax COVID Restrictions

Doctor David Aronoff counters the argument with the facts that the COVID-19 pandemic has now raged on for more than a year. In the U.S., we have documented more than 24.5 million cases and 400,000 COVID-19-related deaths, with between 3,000 and 4,000 people dying each day. The CDC projects we will reach nearly 500,000 total deaths within the next month. COVID-19-related hospitalizations remain at an all-time high. America continues to suffer through a third wave of disease activity that has dwarfed the peaks of the Spring and Summer of 2020.

And, while COVID-19 is beating down on us, it could be worse, believe it or not. We have learned much about how the SARS-CoV-2 virus spreads, easily, through our breath from one person to another. Most nefarious has been the extent to which transmission occurs silently, moving from infected individuals who feel well, look well, and have no idea that they are infected. However, we know that maintaining our distance from others protects against transmission, as does the use of cloth face-coverings. It has been through social distancing and mask use that we have, in the absence of vaccination and herd immunity, been able to limit the damage done by this horrible infectious disease.

Clearly, vaccines against SARS-CoV-2 are the light at the end of the tunnel, assuming that viral mutations do not escape our vaccines sooner than we can put out the fire. With estimates that more than 60% of the population will need to have immune protection against SARS-CoV-2 to benefit from herd immunity, we have a long way to go. While less than 10% of the U.S. population has been formally diagnosed with COVID-19, a recent estimate suggested that by November of 2020 we were at about 15% of the U.S. population immune to the virus. And while that figure may now exceed 20%, this leaves more than 250 million Americans without immune protection, and falls short of the roughly 200 million people who might need to be immune for herd immunity to take hold.

Vinay Prasad, MD, MPH, has authored a thoughtful, evidence-based commentary, making a strong case for why we can relax some restrictions following successful immunization against SARS-CoV-2. He succinctly lays out an argument about why and how immunization, in the absence of vaccine-escaping virus mutants, will confer strong enough protection to render tight adherence to wearing masks and other restrictions unnecessary. And, while I think he has the right idea (I would love to see more people’s faces right now and share a meal with my friends), it is premature to suggest that now is that time. It is OK for us to hold differing opinions (that’s what we do). Two well-intentioned scientists can both look at the same data and reach different policy conclusions. So, let me focus on the case for keeping our masks on, even as we roll our sleeves up. The same logic holds for other restrictions.

First, given how active COVID-19 is right now we need to be doing everything in our power to slow its spread. Lives hang in the balance. I really like the Swiss Cheese model of pandemic defense, popularized by Australian virologist Ian Mackay, PhD, which demonstrates the concept that each measure we implement to interrupt the SARS-CoV-2 pandemic is imperfect yet when layered together they cooperatively reduce transmission risk.

Even immunization is not a perfect defense. Thus far, SARS-CoV-2 vaccination has not been shown to eliminate the risk that someone will get infected or pass the virus on to others. Studies published to date on the Moderna and Pfizer-BioNTech mRNA vaccines show clear protection against developing symptomatic COVID-19. But they also show that some vaccinated people still develop symptomatic disease. And, given what we know about the disease in non-immune people, symptomatic infections represent a fraction of total infections. This predicts that despite immunization some people will develop asymptomatic infection. Do I think that SARS-CoV-2 immunization will significantly protect people against both asymptomatic and symptomatic COVID-19? Yes. Do I think the risk to an individual will be zero following successful immunization? No. Stated differently, removing masks from vaccinated people (or relaxing social distancing) is likely to increase the risk for propagating COVID-19 compared to maintaining these restrictions. And, even if that incremental risk is small, why take it, given where we are with the disease now?

There will be a time when immune people can let their guards down, allowing even non-immune people to do the same (a benefit of herd immunity). But that time is not now.

The issue of wearing masks has been a contentious one, not helped by mixed messaging from leaders in the federal and state government. This has translated into story after story of difficulty convincing people of the public health benefit of wearing face-coverings. What we do not need are more people out and about in public spaces without masks, which sends the wrong message at the wrong time. We cannot know if an unmasked person is unvaccinated or simply an anti-masker. Why provide fuel for people to skirt mask policies based on stating they have been vaccinated, when they might not have been? And the same holds for hosting dinner parties or participating in other gatherings.

To safely advise people that once they are immunized, they can leave their masks at home and relax other infection control measures we need to record sustained decreases in disease activity, hospitalizations, and deaths, to the point where leading infectious disease and public health experts are comfortable recommending that we can de-escalate these interventions. We also need to ensure widespread vaccine uptake, particularly among Black, indigenous, and people of color, who have been disproportionately harmed by COVID-19. Recent data show that Black Americans, for example, are getting vaccinated at lower rates than white Americans.

We remain in the thick fog of a true healthcare emergency and need to be doing all we can, especially the simple things, to shut it down. Now is not the time to let up on masking, even for the relatively few who have been immunized. Abandoning mask-wearing and social distancing, even in immunized persons, is not the right thing to recommend, yet. We need masks on and sleeves up.

COVID-19 Variants: ‘The Virus Still Has Tricks Up Its Sleeve’

Now more on the counterpoint reported by Molly Walker who interviewed Dr. Warner Greene as followed: We are honored to be joined once again by Dr. Warner Greene. He’s senior investigator at Gladstone Institutes and a professor at University of California San Francisco. As we’ve discussed, COVID-19 variants are very much in the news. Can we go over what is the latest news about the variants, even today? What do we know about them and what’s the latest that’s been happening?

Variants are very much in the news. What we’re seeing is the slow but steady evolution of the coronavirus. There are now four major variants that are of concern. And, in fact, they call them variants of concern. The first recognized was the U.K. variant, recognized in the south of the United Kingdom. It has an increased transmission efficiency. And there are some reports that it may be somewhat more virulent, particularly in men over the age of 60.

Of even greater concern is the South African variant, which contains mutations that confer resistance to certain monoclonal antibodies, like one of the two monoclonal antibodies developed by Regeneron. The Eli Lily monoclonal antibody doesn’t seem to work against the South African variant and vaccine efficiency is also reduced with the South African variant.

Similarly, the Brazilian variant has basically the same set of mutations that are conferring antibody resistance, causing real concern. What it means for the vaccines, etc.: I think that both the South African and the Brazilian variants are a major concern. And it is possible that those variants as they spread, and they are in the United States now, we may need to revise the vaccines to account for these types of variants. That’s not clear yet, but better to be prepared, in case we do need to revise the vaccine.

And then there’s a fourth type of variant, which is just kind of emerging, less well-studied at this point, but out of California. So clearly there, the virus is searching for a lock and key mechanism trying to search for ways to allow itself to replicate better. We’re applying immune pressure. So, it’s mutating away from some of that immune pressure, and that’s why this antibody resistance is emerging.

So, what types of mutations does the SARS-CoV-2 virus have to go through to make it a variant?

Well, for example, the South African variant has 27 mutations, nine of which occur in the spike protein. The spike is the protein on the surface that binds to the ACE2 receptor and allows entry and fusion into the host cell. And, of course, that’s where most of the vaccines are focused, is on the spike. That’s where the monoclonal antibody therapeutics are focused, on the spike. And so the virus is looking for ways to avoid these types of immune pressures and it’s making mutations in its receptor binding domain and the internal domain that confer resistance to certain types of neutralizing antibodies.

Given that recent studies from Novavax and Johnson & Johnson last week found somewhat reduced clinical efficacy of vaccines against these variants, what type of booster modification is required for vaccines in order to better combat them with the mRNA and the viral vector vaccines? Is it different, is it the same?

I think the booster that, for example, Moderna and Pfizer are now working on is to take the genetic sequence of the variant and use that as the immunogen. So, there is a mutation at position 484 that is absolutely key for this loss of antibody protection. You would introduce an RNA that now has that same mutation at position 484 into the vaccine to create a vaccine that is really tailored to take that particular type of virus out. And that mutation is shared between the South African and the Brazilian variants.

And so it wouldn’t require a different type, depending on the type of vaccine, it would just be the same type of reformulation. It wouldn’t be mRNA, different than a viral vector, it would just be a different formula. It’s not anything to do with the type of vaccine. It still would be an mRNA-based vaccine. It would just contain a different RNA or more likely it will be a multi-valent vaccine that would be original virus, as well as a new virus.

It’s not clear exactly how that would be administered. It may be that we want to boost immunity against the old virus, as well as the new virus, so we would use a multi-valent approach in that case. But the mRNA vaccine platform is quite amenable to this type of updating. That’s a real advantage, much more so than the adenoviral vectors, the virus-delivered vaccines. It’s a more complicated process there.

If we could just look at the vaccines as we have them now against this wild-type strain, if for some reason we didn’t have any boosters, what type of progress could we make against the pandemic? Can we vaccinate our way out of the pandemic, even if we don’t have these boosters? Have these variants prevented that?

To be clear, these variants, the Brazilian and the South African variants, are only compromising the neutralizing antibody response against the coronavirus. The T-cell immune response presumably is fully intact and remains unevaluated. So it’s quite possible that these vaccines will stand up better than we expect or predict. Clearly the U.K. variant does not appear to be a threat, although the recent acquisition of the neutralizing mutation at 484 causes concern that the virus is evolving. Even the U.K. variant is evolving.

I would say that the one thing that is disturbing to me, or that causes me pause is the story in Manaus, Brazil. Manaus is in the Amazon basin, they had a huge outbreak in the spring. It was thought, as reported, that there would probably be herd immunity within the community up to about 75%. Then this variant comes in to the community and it’s just sweeping through, causing re-infection or what appears to be re-infection.

Now did the original immunity wane and these people were all sensitive? Is it just that the variant is able to avoid both the T-cell and the antibody response that was present in the herd in Manaus? That kind of real-time experiment is concerning in terms of the spread of this virus. And I think data like that and what’s going on in South Africa is what’s really prompting the vaccine companies to get prepared now. We don’t know the full dimensions of the problem, but better to overprepare at this point in time.

So, given what happened in Brazil, do you think that’s evidence of viral escape?

Certainly, the South African and Brazilian variants, the mutations they are acquiring in their spike protein are examples of escape from the antibody neutralization. These are mutating principal antibody-binding sites that are responsible for neutralization, so that these variants are emerging under the influence of immune pressure. It’s harder to get around the T-cell immunity though, because T-cell immunity differs from person to person based on the composition of our HLA genes and our immune response. And T-cells are really the major defense mechanism against viruses, so let’s hope that our T-cells fill in for any gaps that the antibodies might come up a little short on.

I’m not sure exactly what has happened in Manaus, whether there was really ever herd immunity, whether it’s waned, but I do know that the variant there is hitting hard. So, that’s a big question mark. I think Brazil holds the answers to a lot of the future of this pandemic. We need to understand precisely what is going on there.

What do we need to be studying in Brazil specifically? And what type of data would we need to be looking at and tracking, what types of real-world studies and epidemiological studies would you like to see out of what’s happening in Brazil to help us going forward?

I would like to know whether or not there was real herd immunity. Before this new variant began to spread, was there clear evidence of a good antibody response and retention of durable antibody responses against the original strain of “wild-type” virus. So, if, in fact, there was an intact immune response, and this virus was able to overwhelm that response, well that’s not good news, but if the response had waned or had never really developed fully, then that’s a less daunting problem.

Now on the positive side, you look at the Johnson & Johnson vaccine, it’s not the world’s best at preventing you from becoming infected with or developing minor respiratory symptoms. But even with the South African variant, this vaccine protects you from severe disease, having to go to hospital and dying. And frankly, that’s what we want from a vaccine. That is fantastic. You may have a runny nose or a mild upper respiratory tract infection, but you’re not going to develop life-threatening pneumonia and require hospitalization, intubation, etc. And I’d sign up for that type of vaccine any day.

All we have from the mRNA vaccines from Pfizer and Moderna are these kinds of in vitro and in lab studies that if you expose them to these variants, this is what they’ll do, but do we need some type of clinical efficacy? Would you say at this point that we don’t have evidence of clinical efficacy against the variants with these two vaccines that are currently being distributed?

Exactly. The mRNA vaccines are not being tested extensively in areas where the variants are prospering, but one of the trial sites for Johnson & Johnson was in South Africa. So, they were able to see how their vaccines stood up against that variant and it fared very well in terms of prevention of serious disease.

When do you think that we are going to get these types of studies? Is that something that we’re going to see as the vaccine trials kind of evolve, and are we going to be able to get that from the mRNA vaccines? Are we just going to not know what their clinical efficacy is until we get a booster, we’re just going to only have the lab evidence?

It’s likely that the virus is probably replicating at higher levels or more virus is replicating in terms of country here in the United States than almost anywhere else in the world, in terms of the breadth of cases that we’ve had, etc. We just simply do not have the genomic surveillance types of apparatus to necessarily detect these variants. For example, we’re just now detecting the California variants. There may be many variants in the United States. We do know that the Brazilian, as well as the South African, variants are in the United States, and it’s possible that there is community spread of these variants. So, we just have to really ramp up our sequencing efforts to really track what’s happening within our pandemic within the country and what types of viruses that we’re dealing with.

And it’s in that kind of setting as variants begin to hold sway. For example, it’s suggested that the U.K. variant will become dominant in the United States by March. So, our prediction is that the current vaccines will do very well against that variant. Now, if that variant is replaced by, for example, a South African variant, which is more immunologically daunting, well then, we’re going to have to see how the mRNA vaccines hold up against that. And it’s that kind of real-world information that’s going to inform whether or not we need to boost the immune system with a third shot.

Are the variants occurring in regions due to the similarities in the genome of the regional population, causing the viral RNA to mutate in a specific direction, and do antigen tests pick up variants?

No, the antigen tests will not pick up the variants. You really have to do the sequencing to find these mutations. So, it’s clear that the virus has a set of mutations and it’s trying different combinations. All the virus wants to do is to replicate better. The U.K. variant has one mutation in the receptor binding domain, which confers tighter binding to the ACE2 receptor and a higher level of transmission by 40% to 70%. And that’s the variant that may become dominant here in the United States by March. In contrast, the South African and the Brazilian variants, they not only have the same mutation that the U.K. variant does, they’ve added to it. They’ve added at least two additional mutations that really take out these neutralizing antibodies.

Now, did these two variants arise independently? Some would say yes. I don’t think that we know precisely because one person coming from South Africa carrying the virus could seed the virus in Brazil. So, we don’t know, but there are subtle differences. The virus is working toward a solution here for avoiding the antibodies.

Now, another question is, is the virus throwing everything at us right now that it’s got? Is this it and can we expect a pretty much static situation from here on out? And, you know, I don’t think so. I think the virus still has tricks up its sleeve, and will continue to evolve as we put additional immune pressures on it. So, that would be my guess, but we’re right at the cusp of the evolving science. And to think that where we were a year ago with no defense, no innate or no intrinsic immunity to this virus, and nothing really therapeutic or preventive. And now we’re in a situation where we have multiple, highly effective vaccines. It’s a true triumph of science.

Can you go into how else the virus could mutate? Is there any way that it could mutate that T-cell immunity that we have that would be compromised? Is that possible or is it just not that complex a virus?

Yeah, there may be the emergence of escape mutations that escape a cytotoxic T-cell, CD8 T-cell responses, or CD4 helper T-cell responses. We could certainly see that and it’s much harder to monitor for those types of immune reactions. So, certainly, like you get immune escape against antibodies, you can have immune escape against T-cell immunity as well.

California man tests positive for COVID-19 weeks after second jab: report

Edmund DeMarche reported that a California man said he was diagnosed with COVID-19 three weeks after he received his second dose of the vaccine, reports said.

CBS Los Angeles reported that Gary Micheal, who lives in Orange County’s Lake Forest, found out he had the virus after being tested for an unrelated health concern. His symptoms are relatively minor, the report said.

He received the Pfizer vaccine, the report said. Patch.com reported that he got his first dose on Dec. 28 and his second jab on Jan. 18.

Dr. Anthony Fauci, the country’s leading infectious-disease scientist, said the latest evidence indicates that the two vaccines being used in the U.S. — Pfizer’s and Moderna’s — are effective even against the new variants.

A doctor interviewed in the CBS report said that he was not surprised to hear about Michael’s diagnosis.

“I think I’ve heard of six or seven independent cases over the last three weeks of individuals that have been vaccinated with different timelines that have tested positive, and I think we’re going to continue to see that more and more,” Dr. Tirso del Junco Jr., chief medical officer of KPC Health, told the station.

Fauci has estimated that somewhere between 70% and 85% of the U.S. population needs to get inoculated to stop the pandemic that has killed close to 470,000 Americans.

And Now Four people in Oregon who received both doses of vaccine test positive for coronavirus

Minyvonne Burke reported that four people in Oregon have tested positive for the coronavirus after receiving both doses of the Covid-19 vaccine, health officials said.

There are two cases each in Yamhill and Lane counties, the state’s Health Authority said in a series of tweets on Friday. The cases are either mild or asymptomatic.

“We are working with our local and federal public health partners to investigate and determine case origin,” the agency said. “Genome sequencing is underway, and we expect results next week.”

The agency referred to the individuals who tested positive as “breakthrough cases,” meaning that they got sick with the virus at least 14 days after receiving both doses.

The Health Authority said more breakthrough cases could pop up.

“Clinical trials of both vaccines presently in use included breakthrough cases. In those cases, even though the participants got Covid, the vaccines reduced the severity of illness,” the agency said in a tweet.

“Based on what we know about vaccines for other diseases and early data from clinical trials, experts believe that getting a Covid-19 vaccine may also help keep you from getting seriously ill even if you do get the virus. … Getting as many Oregonians as possible vaccinated remains a critical objective to ending the pandemic.”

The agency’s announcement came the same day its health officer said there has been a decline of daily Covid-19 cases over the past several weeks. As of Friday, there were 149,576 cases in the state, according to the department’s count.

“These decreases are a testament to the actions all Oregonians are taking to slow the spread of Covid-19 and the sacrifices made – thank you,” health officer Dean Sidelinger said at a news conference Friday.

Another breakthrough case was reported in North Carolina, according to NBC affiliate WCNC-TV in Charlotte. The state’s Department of Health and Human Services told the outlet that the person had mild symptoms and did not need to be hospitalized.

The Centers for Disease Control and Prevention has said that quarantining is not necessary for fully vaccinated people within three months of having received their last doses as long as they do not develop any symptoms.

They do, however, still need to practice certain safety measures such as wearing face masks, social distancing, and avoiding crowds or poorly ventilated spaces.

“Fully vaccinated” means at least two weeks have passed since a person has completed their vaccination series and now we have the addition of the Johnson and Johnson vaccine, which is a single dose with less effectivity but about the same activity of our yearly flu vaccine.

So, as I have said before, continue to wear your masks, whether one, two, three or whatever the number of masks that we are going to be advised with future “scientific” evidence.

Another New COVID Strain Is in the US; Will Present Vaccines Work with these New Strains, Pandemic Strategies Including New Migrants and What Happened to Merck’s Vaccine?

This has been an interesting few week and almost led me to close my office and retire. We had a patient come in the office and complete the questionnaire and “by-pass” our screening procedures, lying to us about his exposure to the COVID-19 virus. He just visited his brother the two days before the days office visit and lied to us, saying that he had no recent exposure, etc. However, a week later he called our office to allow notification that his COVID test was positive.

The thing that angered me and my staff more was that the patient waited a number of days to notify, besides lying to us about his exposure. This led us to close the office, cancel all patients until we could have a complete cleaning of the office and all get COVID tested.

Luckily, we all tested negative and all my staff and I had at least had our first vaccine doses. If we had tested positive, we would have to notify all the patients that were seen in the office between his visit and the day that we closed the office.

What an irresponsible set of actions and my fear is that this goes on in many situations because many of our patients, etc. are selfish and irresponsible and don’t care about anyone else except themselves…and they think the virus is all a lie, util one of their family members or close friends dies. How totally stupid and disgusting!! 

John Johnson wrote that the virus continues to mutate quickly. Anyone tracking the news is familiar with the new UK strain that is moving around the globe and threatens to become the dominant strain in the US soon. Now, health authorities in California have identified yet another strain that has popped up in about a dozen counties, reports the Los Angeles Times. Coverage on that and more:

  • California strain: The variant has been linked to large outbreaks in Santa Clara County and smaller outbreaks elsewhere. It’s still too early to say whether the new strain is more contagious or more lethal than the first forms of COVID that emerged, but studies on that are being prioritized. Bottom line: “This virus continues to mutate and adapt, and we cannot let down our guard,” says Dr. Sara Cody, Santa Clara County health officer.
  • A lament: In a New York Times op-ed, Ezra Klein runs through the coming COVID changes under the Biden administration. They include plans to get vaccinations organized on a mass scale, along with expanded testing and contract tracing. It’s all pretty basic stuff, he writes, which has him astonished that the Trump administration hasn’t done these things yet. “That it is possible for Joe Biden and his team to release a plan this straightforward is the most damning indictment of the Trump administration’s coronavirus response imaginable.”
  • Hopeful trend: US deaths are about to pass 400,000, but one medical expert spies a positive trend in the new data as well. “Over the last four days for the first time in months, we’ve seen a steady decline … a thousand per day fewer hospitalizations in the United States,” Dr. Jonathan Reiner of George Washington University tells CNN. “We’ve seen the same trend in new cases.” The next two months will likely be brutal, he adds, “but there is a ray of sunshine” as vaccinations continue.
  • Hopeful, II: In “The Morning” newsletter at the Times, David Leonhardt is tired of the “they’re only 95% effective” drumbeat, and he’s not alone. “It’s driving me a little bit crazy,” Dr. Ashish Jha of the Brown School of Public Health tells Leonhardt. Dr. Aaron Richterman of the University of Pennsylvania adds, “We’re underselling the vaccine.” As Leonhardt explains and doctors emphasize, the vaccine will save your life, even if you’re in that other 5%. To wit, of 32,000 people who got the Pfizer and Moderna vaccines in trials, only one person suffered a severe COVID case.

Migrant caravan demands Biden administration ‘honors its commitments’

Now, a real challenge for the new Biden administration. Adam Shaw noted that a migrant caravan moving from Honduras toward the U.S. border is calling on the incoming Biden administration to honor what it says are “commitments” to the migrants moving north, amid fears of a surge at the border when President-elect Joe Biden enters office.

More than 1,000 Honduran migrants moved into Guatemala on Friday without registering, The Associated Press reported. That is part of a larger caravan that left a Honduran city earlier in the day.

The outlet reported that they are hoping for a warmer reception when they reach the U.S. border, and a statement issued by migrant rights group Pueblo Sin Fronteras, on behalf of the caravan, said it expects the Biden administration to take action.

“We recognize the importance of the incoming Government of the United States having shown a strong commitment to migrants and asylum seekers, which presents an opportunity for the governments of Mexico and Central America to develop policies and a migration management that respect and promote the human rights of the population in mobility,” the statement said. ” We will advocate that the Biden government honors its commitments.” 

Biden has promised to reverse many of Trump’s policies on border security and immigration. He has promised to end the Migrant Protection Protocols (MPP), which keeps migrants in Mexico as they await their hearings. The Trump administration has said the program has helped end the pull factors that bring migrants north, but critics say it is cruel and puts migrants at risk. 

Biden has also promised a pathway to citizenship for those in the country illegally and a moratorium on deportations by Immigration and Customs Enforcement (ICE). The migrants’ group also pointed to promises to end the asylum cooperative agreements the administration made with Northern Triangle countries.

“A new United States Government is an opportunity to work with the Mexican Government to develop a cooperation plan with Central America to address the causes of migration, together with civil society organizations, as well as an opportunity to increase regional cooperation regarding the persons in need of protection, and to dismantle illegal and inhuman programs such as Remain in Mexico, the United States’ Asylum Cooperation Agreements with El Salvador, Guatemala and Honduras, as well as the Title 42 expulsions by the United States authorities,” it said, referring to the Centers for Disease Control (CDC) order that allows the U.S. to quickly remove migrants on public health grounds.

Biden officials, however, have been keen to send the message to migrants that it will not mean open borders overnight.

“Processing capacity at the border is not like a light that you can just switch on and off,” incoming Biden domestic policy adviser Susan Rice told Spanish wire service EFE. “Migrants and asylum seekers absolutely should not believe those in the region peddling the idea that the border will suddenly be fully open to process everyone on Day 1. It will not.” 

“Our priority is to reopen asylum processing at the border consistent with the capacity to do so safely and to protect public health, especially in the context of COVID-19,” she said. “This effort will begin immediately but it will take months to develop the capacity that we will need to reopen fully.”

It is unclear how far the migrants will get, and Guatemalan and Mexican governments have indicated they intend to turn them back. But the caravan comes amid fears that the new outlook on immigration and asylum from the Biden administration will fuel a surge at the border.

Acting Customs and Border Protection (CBP) Commissioner Mark Morgan said on “America’s News HQ” on Saturday that the caravan could include more than 5,000 migrants and blamed the tone from the incoming administration.

“We’re looking at two groups that are well over five thousand. And one of those groups have already gotten through the Guatemala border. And they’re on their way to El Rancho, which is about the located centrally in Guatemala,” he said. “It’s coming. It’s already started, just as we promised and anticipated it would with this rhetoric from the new administration on the border.”

President Trump warned this week that ending his policies and increasing incentives would lead to “a tidal wave of illegal immigration, a wave like you’ve never seen before” and that there were already signs of increased flows.

“They’re coming because they think that it’s a gravy train at the end,” he said. “It’s going to be a gravy train. Change the name from the caravans, which I think we came up with, to the gravy train because that’s what they’re looking for — looking for the gravy.”

Biden transition official tells migrant caravans: ‘Now is not the time’ to come to US

Yael Halon reported further on the migration noting that a migrant caravan moving from Honduras toward the U.S. border called on the incoming Biden administration to honor their “commitments” to the migrants moving north, citing the incoming administration’s vow to ease Trump’s restrictions on asylum.

But on Sunday, an unnamed Biden transition official said that migrants hoping to claim asylum in the U.S. during the first few weeks of the new administration “need to understand they’re not going to be able to come into the United States immediately,” NBC News reports. 

More than 1,000 Honduran migrants moved into Guatemala on Friday without registering as part of a larger caravan that left a Honduran city earlier in the day.

The Associated Press reported that they are hoping for a warmer reception when they reach the U.S. border, and a statement issued by migrant rights group Pueblo Sin Fronteras, on behalf of the caravan, said it expects the Biden administration to take action.

The Biden transition official, however, warned migrants against coming to the U.S. during the early days of the new administration, telling NBC that while “there’s help on the way,” now “is not the time to make the journey.” 

“The situation at the border isn’t going to be transformed overnight,” the official told the outlet.

“We have to provide a message that health and hope is on the way, but coming right now does not make sense for their own safety…while we put into place processes that they may be able to access in the future,” the official said.

President-elect Joe Biden has promised to reverse many of Trump’s policies on border security and immigration. He has promised to end the Migrant Protection Protocols (MPP), which keeps migrants in Mexico as they await their political asylum hearings. The Trump administration has said the program has helped end the pull factors that bring migrants north, but critics say it is cruel and puts them at risk. 

Biden has also promised a pathway to legal permanent residency for those in the country illegally and a moratorium on deportations by Immigration and Customs Enforcement (ICE). The migrants’ group also pointed to promises to end the asylum cooperative agreements the administration made with Northern Triangle countries.

President Trump warned last week that ending his policies and increasing incentives would lead to “a tidal wave of illegal immigration, a wave like you’ve never seen before,” claiming that there were already signs of increased flows.

AMA President: Biden Team Must Create National Pandemic Strategy

Ken Terry stated that now that the campaign is over, that the incoming Biden administration must formulate an effective national strategy for the COVID-19 pandemic, said Susan R. Bailey, MD, president of the American Medical Association (AMA), in a speech delivered today at the National Press Club in Washington, DC.

Bailey noted that America’s fight against the pandemic is in a critical phase, as evidenced by the escalation in cases, hospitalizations, and deaths in recent weeks. Emergency departments and ICUs are overwhelmed; many frontline clinicians are burned out; and the state- and local-level mechanisms for vaccine distribution have been slow and inconsistent, she said.

“The most important lesson for this moment, and for the year ahead, is that leaving state and local officials to shoulder this burden alone without adequate support from the federal government is not going to work,” Bailey emphasized.

She called on the Biden administration, which takes over next week, to “provide states and local jurisdictions with additional resources, guidance, and support to enable rapid distribution and administration of vaccines.”

In addition, she said, the incoming administration needs to develop a more robust, national strategy for continued COVID-19 testing and PPE production “by tapping into the full powers of the Defense Production Act.”

Biden Vaccine Distribution Policy

In a question-and-answer period following her speech, however, Bailey said she opposed the president-elect’s decision to release nearly all available vaccine supplies immediately, rather than hold back some doses for the second shots that the Pfizer and Moderna vaccines require. On Tuesday, the Trump administration announced that it plans to do the same thing.

“We’re a little bit concerned about the announcement that [the Department of Health & Human Services] will not hold back vaccine doses to make sure that everyone who’s gotten their first dose will have a second dose in reserve,” Bailey said. “We don’t have adequate data to tell us that one dose is sufficient — we don’t think it is — and how long you can wait for the second dose without losing the benefits of the first dose.”

She added that it’s not recommended that people mix the two vaccines in the first and second doses. “Since the Pfizer vaccine has such rigid storage requirements, I want to make sure there’s plenty of vaccine for frontline healthcare workers who got the Pfizer vaccine because it was the first one to come out in December. I want to make sure they get their second dose on time and [do] not have to wait.”

Bailey said she hoped there will be plenty of vaccine supply. But she suggested that state and local health authorities be in communication with the federal government about whether there will be enough vaccine to guarantee people can get both doses.

Bolstering Public Health

In her speech, Bailey outlined five areas in which steps should be taken to improve the health system so that it isn’t overwhelmed the next time the US has a public health crisis:

  • Restore trust in science and science-based decision making. Make sure that scientific institutions like the Centers for Disease Control and Prevention and the Food and Drug Administration are “free from political pressure, and that their actions are guided by the best available scientific evidence.”
  • Ensure that the health system provides all Americans with affordable access to comprehensive healthcare. Bailey wasn’t talking about Medicare for All; she suggested that perhaps there be a second enrollment period for the Affordable Care Act’s individual insurance exchanges.
  • Work to remove healthcare inequities that have hurt communities of color, who have been disproportionately impacted by the pandemic. She referred to a recent AMA policy statement that recognized racism as a public health threat.
  • Improve public health domestically and globally. Among other things, she noted, the public health infrastructure needs to be revitalized after “decades of disinvestment and neglect,” which has contributed to the slow vaccine rollout.
  • Recognize the global health community and restore America’s leadership in global efforts to combat disease, which are critical to preventing future threats. She praised Biden for his promise that the US will rejoin the World Health Organization.

At several points in her presentation, Bailey rejected political interference with science and healthcare. Among other things, she said public health could be improved by protecting the doctor-patient relationship from political interference.

Answering a question about how to separate politics from the pandemic, she replied, “The key is in sticking to the science and listening to our public health authorities. They all have to deliver the same message. Also, leaders at all levels, including in our communities, our schools, churches and college campuses, should wear masks and socially distance. This isn’t about anything other than the desire to get out of the pandemic and get our country on the right track again. Masks shouldn’t be political. Going back to school shouldn’t be political. Taking a certain medication or not shouldn’t be political. We need to stick to the science and listen to our public health authorities. That’s the quickest way out.”

Asked when she thought that life might get back to normal again in the US, Bailey said a lot depends on the extent of vaccine uptake and how much self-discipline people exhibit in following public health advice. “I think we’re looking at the end of this year. I’m hopeful that by fall, things will have opened up quite a bit as the Venn diagrams of those who’ve gotten vaccines grow larger.”

Merck Ends Development of Two Potential COVID-19 Vaccines

Tom Murphy, AP Health Writer, pointed out that the drug maker, Merck, said Monday that it will focus instead on studying two possible treatments for the virus that also have yet to be approved by regulators. The company said its potential vaccines were well tolerated by patients, but they generated an inferior immune system response compared with other vaccines.

Merck was developing one of the potential vaccines with France’s Pasteur Institute based on an existing measles vaccine. The French institute said it will keep working on two other vaccine projects using different methods.

Merck entered the race to fight COVID-19 later than other top drug makers.

It said last fall that it had started early-stage research in volunteers on potential vaccines that require only one dose. Vaccines developed by Pfizer and Moderna were already in late-stage research at that point.

The Food and Drug Administration allowed emergency use of both the Pfizer and Moderna vaccines late last year. Each requires two shots.

Five potential vaccines have reached late-stage testing in the United States, the final phase before a drug maker seeks approval from regulators. Results from a single-dose candidate developed by Johnson & Johnson are expected soon.

Since vaccinations began in December, nearly 22 million doses have been delivered to people nationwide, according to the Centers for Disease Control and Prevention. Nearly 6% of the population has received at least one dose.

A total of 3.2 million people, or 1% of the population, have received both doses required for those vaccines.

More than 419,000 people in the United States and 2 million globally have died due to the coronavirus, according to Johns Hopkins University.

The government is paying Merck & Co. about $356 million to fast-track production of one of its potential treatments under Operation Warp Speed, a push to develop COVID-19 vaccines and treatments. The money will allow the Kenilworth, New Jersey, company to deliver up to 100,000 doses by June 30, if the FDA clears the treatment for emergency use.

The treatment, known as MK-7110, has the potential to minimize the damaging effects of an overactive immune response to COVID-19. This immune response can complicate the life-saving efforts of doctors and nurses.

Merck said early results from a late-stage study of that drug showed a more than 50% reduction in the risk of death or respiratory failure in patients hospitalized with moderate or severe COVID-19. The company expects full results from that study in the first quarter.

Merck’s other potential treatment is an oral antiviral drug.

Merck said it will focus COVID-19 research and manufacturing efforts on two investigational medicines: MK-7110 and MK-4482, which it now calls molnupiravir. Molnupiravir, which is being developed in collaboration with Ridgeback Bio, is an oral antiviral being studied in both hospital and outpatient settings. If these oral antiviral drugs are effective this will be a real advancement in the treatment of COVID-19. Merck said a phase 2/3 trial of the drug is set to finish in May, but initial efficacy results are due in the first quarter and will be made public if clinically meaningful. 

Merck said results from a phase 3 study of MK-7110, an immune modulator being studied as a treatment for patients hospitalized with severe COVID-19, are expected in the first quarter. In December, the company announced a deal to supply MK-7110 to the U.S. government for up to about $356 million. (Reporting by Deena Beasley Editing by Shri Navaratnam)

Moderna Study: Vaccine Effective vs COVID Variants

With the weekly announcement of new mutant strains of the COVID virus we are all wondering whether the vaccine that are being administered will be effective against the new strains. Carolyn Crist noted that as mutated strains of the coronavirus represent new threats in the pandemic, vaccine makers are racing to respond.

Moderna, whose two-dose vaccine has been authorized for use in the U.S. since Dec. 18, said Monday that it is now investigating whether a third dose of the vaccine will work to prevent the spread of a variant first seen in South Africa, while it also tests a new vaccine formula for the same purpose.

“Out of an abundance of caution and leveraging the flexibility of our mRNA platform, we are advancing an emerging variant booster candidate against the variant first identified in the Republic of South Africa into the clinic to determine if it will be more effective … against this and potentially future variants,” Moderna CEO Stephane Bancel said in a statement.

Moderna on Monday also said its COVID-19 vaccine could protect against the U.K. strain but that it is less effective against the strain identified in South Africa.

Pfizer and BioNTech, whose vaccine were also authorized in December, announced last week that their COVID-19 vaccine creates antibodies that could protect vaccine recipients from the coronavirus variant first identified in the United Kingdom.

“This is not a problem yet,” Paul Offit, MD, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told CNBC.

“Prepare for it. Sequence these viruses,” he said. “Get ready just in case a variant emerges, which is resistant.”

There were at least 195 confirmed cases of patients infected with the U.K. variant in the U.S. as of Friday, according to the CDC. No cases from the South African variant have been confirmed in the U.S. To try and prevent the variant from entering the country, President Joe Biden plans to ban travel from South Africa, except for American citizens and permanent residents.

The U.S. has reported more than 25 million total COVID-19 cases, according to data from Johns Hopkins University, marking another major milestone during the pandemic.

That means about 1 in 13 people in the U.S. have contracted the virus, or about 7.6% of the population.

“Twenty-five million cases is an incredible scale of tragedy,” Caitlin Rivers, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, told The New York Times. She called the pandemic one of the worst public health crises in history.

After the first U.S. case was reported in January 2020, it took more than 9 months to reach 10 million cases in early November. Numbers rose during the holidays, and 10 million more cases were reported by the end of the year. Following a major surge throughout January, with a peak of more than 300,000 daily cases on some days, the U.S. reached 25 million in about 3 weeks.

Hospitalizations also peaked in early January, with more than 132,000 COVID-19 patients in hospitals across the country, according to the COVID Tracking Project. On Sunday, about 111,000 patients were hospitalized, which is the lowest since mid-December.

The U.S. has also reported nearly 420,000 deaths. As recently as last week, more than 4,400 deaths were reported in a single day, according to the COVID Tracking Project. Deaths are beginning to drop but still remain above 3,000 daily deaths.

The University of Washington’s Institute for Health Metrics and Evaluation released a new projection last week that said new cases would decline steadily in coming weeks. New COVID-19 cases have fallen about 21% in the last 2 weeks, according to an analysis by The New York Times.

“We’ve been saying since summer that we thought we’d see a peak in January, and I think that, at the national level, we’re around the peak,” Christopher J.L. Murray, MD, director of the institute, told the newspaper.

At the same time, public health officials are concerned that new coronavirus variants could lead to an increase again. Murray said the variants could “totally change the story.” If the more transmissible strains spread quickly, cases and deaths will surge once more.

“We’re definitely on a downward slope, but I’m worried that the new variants will throw us a curveball in late February or March,” Rivers told the newspaper.

So, next, when we get vaccinated do we need to wear masks and continue social distancing?

We will explore that set of questions next.
