Cases of COVID-19 have increased during the last 14 days in 10 states and Washington, D.C., with the latest additions of the district and Illinois.
Nationwide, COVID-19 cases decreased 15 percent over the past 14 days, according to HHS data collected by The New York Times. But as the more contagious omicron subvariant BA.2 continues to spread, cases are ticking upward in 10 states and D.C. as of March 25. Cases were moving upward in nine states as of March 24, with D.C. and Illinois reporting increases a day later.
Here are the 14-day changes for cases in each state reporting an increase, according to HHS data collected by The New York Times:
New York: 44 percent
Kentucky: 35 percent
Arkansas: 23 percent
Colorado: 21 percent
Connecticut: 18 percent
Texas: 17 percent
Massachusetts: 15 percent
Vermont: 13 percent
Rhode Island: 11 percent
Washington, D.C.: 5 percent
Illinois: 1 percent
The latest variant proportion estimates from the CDC show the omicron subvariant BA.2 accounts for more than one-third of COVID-19 cases nationwide and more than half of cases in the Northeast. Rhode Island has the highest proportion of BA.2 cases of all states, according to the latest ranking of states by the subvariant’s prevalence.
“If we maintain our preparedness, an increase in cases does not need to be a cause for alarm like it once was,” Jeff Zients, White House COVID-19 response coordinator, said in a March 23 media briefing. “We know what tools we need to fight the virus. Unfortunately, because of congressional action, we’re at risk of not having these tools readily available.”
President Joe Biden signed into law March 15 a sweeping $1.5 trillion bill that funds the government through September. The legislation did not include COVID-19 funding the White House had requested from Congress due to partisan disagreement about offsetting the funding.
There is no clear path to approval of more COVID-19 funding.
The lack of funding is affecting resources for COVID-19 testing and treatment. The Health Resources and Services Administration stopped accepting providers’ claims for COVID-19 testing and treatment of the uninsured March 22 due to a lack of sufficient funds. The federal government is also cutting back shipments of monoclonal antibody treatments to states by 30 percent, and the U.S. supply of those treatments could run out as soon as May.
A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another surge in the U.S. and how best to protect yourself.
What is BA.2, and how is it related to omicron?
BA.2 is the latest subvariant of omicron, the dominant strain of the SARS-CoV-2 virus that causes COVID-19. While the origin of BA.2 is still unclear, it has quickly become the dominant strain in many countries, including India, Denmark and South Africa. It is continuing to spread in Europe, Asia and many parts of the world.
The first omicron subvariant, BA.1, is unique in the number of alterations it has compared to the original version of the virus – it has over 30 mutations in the spike protein that helps it enter cells. Spike protein mutations are of high concern to scientists and public health officials because they affect how infectious a particular variant is and whether it is able to escape the protective antibodies that the body produces after vaccination or a prior COVID-19 infection.
BA.2 has eight unique mutations not found in BA.1, and lacks 13 mutations that BA.1 does have. BA.2 does, however, share around 30 mutations with BA.1. Because of its relative genetic similarity, it is considered a subvariant of omicron as opposed to a completely new variant.
While standard PCR tests are still able to detect the BA.2 variant, they might not be able to tell it apart from the delta variant.
Is it more infectious and lethal than other variants?
BA.2 is considered to be more transmissible but not more virulant than BA.1. This means that while BA.2 can spread faster than BA.1, it might not make people sicker.
Does previous infection with BA.1 provide protection against BA.2?
Yes! A recent study suggested that people previously infected with the original BA.1 subvariant have robust protection against BA.2.
Because BA.1 caused widespread infections across the world, it is likely that a significant percentage of the population has protective immunity against BA.2. This is why some scientists predict that BA.2 will be less likely to cause another major wave
However, while the natural immunity gained after COVID-19 infection may provide strong protection against reinfection from earlier variants, it weakens against omicron.
How effective are vaccines against BA.2?
A recent preliminary study that has not yet been peer reviewed of over 1 million individuals in Qatar suggests that two doses of either the Pfizer–BioNTech or Moderna COVID-19 vaccines protect against symptomatic infection from BA.1 and BA.2 for several months before waning to around 10%. A booster shot, however, was able to elevate protection again close to original levels.
Importantly, both vaccines were 70% to 80% effective at preventing hospitalization or death, and this effectiveness increased to over 90% after a booster dose.
How worried does the US need to be about BA.2?
The rise in BA.2 in certain parts of the world is most likely due to a combination of its higher transmissibility, people’s waning immunity and relaxation of COVID-19 restrictions.
CDC data suggests that BA.2 cases are rising steadily, making up 23% of all cases in the U.S. as of early March. Scientists are still debating whether BA.2 will cause another surge in the U.S.
Though there may be an uptick of BA.2 infections in the coming months, protective immunity from vaccination or previous infection provides defense against severe disease. This may make it less likely that BA.2 will cause a significant increase in hospitalization and deaths. The U.S., however, lags behind other countries when it comes to vaccination, and falls even further behind on boosters.
Whether there will be another devastating surge depends on how many people are vaccinated or have been previously infected with BA.1. It’s safer to generate immunity from a vaccine, however, than from getting an infection. Getting vaccinated and boosted and taking precautions like wearing an N95 mask and social distancing are the best ways to protect yourself from BA.2 and other variants.
Over the next few weeks, the U.S. should expect an increase in cases from the BA.2 variant, Dr. Anthony Fauci told ABC News, but it may not lead to as severe a surge in hospitalizations or deaths.
“I would not be surprised if in the next few weeks we see somewhat of either a flattening of our diminution or maybe even an increase,” Fauci told ABC News’ Brad Mielke on the podcast “Start Here.”
His prediction is based on conversations with colleagues in the U.K., which is currently seeing a “blip” in cases, Fauci said. The pandemic trajectory in the U.S. has often followed the U.K. by about three weeks.
However, he added, “Their intensive care bed usage is not going up, which means they’re not seeing a blip up of severe disease.”
The BA.2 variant, a more transmissible strain of omicron, now represents around 23% of all cases in the U.S., according to the latest data from the Centers for Disease Control and Prevention.
And while Fauci predicted that the BA.2 variant will eventually overtake omicron as the most dominant variant, it’s not yet clear how much of a problem that will be.
“Whether or not that is going to lead to another surge, a mini surge or maybe even a moderate surge, is very unclear because there are a lot of other things that are going on right now,” Fauci said.
Similar to the U.K., much of the U.S. has recently relaxed mitigation efforts like mask mandates and requirements for proof of vaccination. At the same time, people who were vaccinated over six months ago and still haven’t gotten a booster shot, which is about half of vaccinated Americans, according to the CDC, are facing continuously waning immunity.
It’s also not yet clear how long immunity from prior infection will last, Fauci said.
Taken together, it’s why Fauci and other experts, including CDC Director Rochelle Walensky, have increasingly predicted that elderly people will need a second booster shot soon. The Food and Drug Administration began reviewing data from Pfizer on the safety and efficacy this week, and its advisory panel will debate if and when the additional booster shot is necessary in the coming weeks.
At the same time, Fauci urged Americans who haven’t yet gotten their first booster, which would be their third shot in a Pfizer or Moderna series, to do so.
A resurgence of cases could also mean Americans are asked to wear masks again, which Fauci predicted would be an uphill battle.
“From what I know about human nature, which I think is pretty much a lot, people are kind of done with COVID,” Fauci said.
Still, he defended the CDC decision to loosen its mask recommendations earlier this month by shifting to a strategy that focused more on severe outcomes, like hospitalizations and deaths, rather than on daily case spread.
“You can go ahead and continue to tiptoe towards normality, which is what we’re doing, but at the same time, be aware that you may have to reverse,” Fauci said.
And if the U.S. does continue to make its way back toward normal times, Fauci himself has a personal choice to consider. At 81 years old, the director of the National Institute of Allergy and Infectious Diseases is “certainly” thinking about retirement.
“I have said that I would stay in what I’m doing until we get out of the pandemic phase and I think we might be there already, if we can stay in this,” Fauci said, referring to the falling cases and hospitalizations in the U.S.
“I can’t stay at this job forever. Unless my staff is gonna find me slumped over my desk one day. I’d rather not do that,” he said, laughing.
While he doesn’t currently have retirement plans, the recent hire of Dr. Ashish Jha, dean of the Brown University School of Public Health, to be White House coronavirus coordinator, could alleviate some of his pandemic response duties and give him a window.
But Fauci, who has dedicated his career to public health, primarily studying HIV and AIDS, and worked under seven U.S. presidents, said he doesn’t have any particular hobbies waiting for him in retirement.
“I, unfortunately, am somewhat of a unidimensional physician, scientist, public health person. When I do decide I’m going to step down, whenever that is, I’m going to have to figure out what it is I’m going to do,” he said.
“I’d love to spend more time with my wife and family. That would really be good.”
A surge in coronavirus infections in Western Europe has experts and health authorities on alert for another wave of the pandemic in the United States, even as most of the country has done away with restrictions after a sharp decline in cases.
Infectious-disease experts are closely watching the subvariant of omicron known as BA.2, which appears to be more transmissible than the original strain, BA.1, and is fueling the outbreak overseas.
In all, about a dozen nations are seeing spikes in coronavirus infections caused by BA.2, a cousin of the BA.1 form of the virus that tore through the United States over the past three months.
In the past two years, a widespread outbreak like the one now being seen in Europe has been followed by a similar surge in the United States some weeks later. Many, but not all, experts interviewed for this story predicted that is likely to happen. China and Hong Kong, on the other hand, are experiencing rapid and severe outbreaks, but the strict “zero covid” policies they have enforced make them less similar to the United States than Western Europe.
A number of variables — including relaxed precautions against viral transmission, vaccination rates, the availability of antiviral medications and natural immunity acquired by previous infection — may affect the course of any surge in the United States, experts said.
Most importantly, it is unclear at this point how many people will become severely ill, stressing hospitals and the health-care system as BA.1 did.
Another surge also may test the public’s appetite for returning to widespread mask-wearing, mandates and other measures that many have eagerly abandoned as the latest surge fades and spring approaches, experts said.
“It’s picking up steam. It’s across at least 12 countries … from Finland to Greece,” said Eric Topol, director of the Scripps Research Translational Institute in San Diego, who recently posted charts of the outbreak on Twitter. “There’s no question there’s a significant wave there.”
Topol noted that hospitalizations for covid-19, the disease caused by the virus, are rising in some places as well, despite the superior vaccination rates of many Western European countries.
At a briefing Monday, White House press secretary Jen Psaki said about 35,000 cases of BA.2 have been reported in the United States to date. But she offered confidence that “the tools we have — including mRNA vaccines, therapeutics and tests — are all effective tools against the virus. And we know because it’s been in the country.”
Kristen Nordlund, a spokeswoman for the Centers for Disease Control and Prevention, said in an email Tuesday that “although the BA.2 variant has increased in the United States over the past several weeks, it is not the dominant variant, and we are not seeing an increase in the severity of disease.”
The seven-day average of cases in the United States fell 17.9 percent in the past week, according to data tracked by The Washington Post, while the number of deaths dropped 17.2 percent and hospitalizations declined 23.2 percent.
Predicting the future course of the virus has proved difficult throughout the pandemic, and the current circumstances in Europe elicited a range of opinions from people who have closely tracked the pathogen and the disease it causes.
In the United States, just 65.3 percent of the population, 216.8 million people, are fully vaccinated, and only 96.1 million have received a booster shot, according to data tracked by The Post. In Germany, nearly 76 percent are fully vaccinated, according to the Johns Hopkins data, and the United Kingdom has fully vaccinated 73.6 percent.
That lower vaccination rate is very likely to matter as BA.2 spreads further in the United States, especially in regions where it is significantly lower than the national rate, several experts said. And even for people who are fully vaccinated and have received a booster shot, research data is showing that immunity to the virus fades over time. Vaccine-makers Pfizer and BioNTech asked the Food and Drug Administration on Tuesday for emergency authorization to offer a fourth shot to people 65 and older.
“Any place you have relatively lower vaccination rates, especially among the elderly, is where you’re going to see a bump in hospitalizations and deaths from this,” said Céline Gounder, an infectious-diseases physician and editor at large for public health at Kaiser Health News.
Similarly, as the public sheds masks — every state has dropped its mask mandate or announced plans to do so — another layer of protection is disappearing, several people tracking the situation said.
“Why wouldn’t it come here? Are we vaccinated enough? I don’t know,” said Kimberly Prather, a professor of atmospheric chemistry and an expert on aerosol transmission at the University of California at San Diego.
“So I’m wearing my mask still. … I am the only person indoors, and people look at me funny, and I don’t care.”
Yet BA.2 appears to be spreading more slowly in the United States than it has overseas, for reasons that aren’t entirely clear, Debbie Dowell, chief medical officer for the CDC’s covid-19 response, said in a briefing Saturday for clinicians sponsored by the Infectious Diseases Society of America.
“The speculation I’ve seen is that it may extend the curve going down, case rates from omicron, but is unlikely to cause another surge that we saw initially with omicron,” Dowell said.
One reason for that may be the immunity that millions of people acquired recently when they were infected with the BA.1 variant, which generally caused less-severe illness than previous variants. Yet no one really knows whether infection with BA.1 offers protection from BA.2.
“That’s the question,” said Jeffrey Shaman, an epidemiologist at the Columbia University Mailman School of Public Health. “Better yet, how long does it provide protection?”
Topol said the United States needs to improve its vaccination and booster rates immediately to protect more of the population against any coming surge.
“We have got to get the United States protected better. We have an abundance of these shots. We have to get them into people,” he said.
Biden administration officials said that whatever the further spread of BA.2 brings to the United States, the next critical step is to provide the $15.6 billion in emergency funding that Congress stripped from a deal to fund the government last week. That money was slated to pay for coronavirus tests, more vaccines and antiviral medications.
“That means that some programs, if we don’t get funding, could abruptly end or need to be pared back, Psaki said at Monday’s briefing. “And that could impact how we are able to respond to any variant.”

Masks come to the Super Bowl: Fans attending the big game next month will be given KN95 masks.
Despite omicron being less severe on average, the sheer number of cases has driven deaths past the peak from last year’s delta surge.
The average number of U.S. COVID-19 deaths this week surpassed the height of the delta surge earlier this fall and is at its highest point since last winter, when the nation was coming out of the peak winter surge.
The seven-day average of deaths hit 2,166 on Monday, according to the latest data from the Centers for Disease Control and Prevention (CDC). Average daily deaths in mid-September before the omicron variant was discovered peaked at around 1,900.
While increasing evidence shows omicron may be less likely to cause death or serious illness than delta, the sheer infectiousness and the speed at which it spreads has overwhelmed hospitals, primarily with people who have not been vaccinated.
The U.S. saw the highest numbers of deaths in the pandemic just over a year ago, before vaccines were widely available, when the daily average reached 3,400. The last time the U.S. topped 2,000 deaths was last February, as the country was slowly coming down from the January peak.
Caution urged: Infections are falling in states that were hardest hit earlier, as well as broadly across the nation. Hospitalizations are also falling, but deaths are a lagging indicator and are still increasing. CDC Director Rochelle Walsenky said deaths have increased about 21 percent over the past week.
The fact that the omicron variant tends to cause less severe disease on average also helped avoid an even greater crisis that would have occurred if it was as severe as the delta variant.
This week the Biden Administration unveiled actions to make at-home COVID tests and N95 masks available, free of charge, to hundreds of millions of Americans. However, even as US COVID hospitalizations have now surpassed last winter’s previous peak, two newly-approved COVID antiviral drugs remain scarce. Just as fast as Omicron has surged across the country, it may be starting to recede, with cases beginning to drop in several states in the Northeast. Modelers now project the incredibly contagious variant will infect 40 percent of Americans and more than half the human race by the end of March.
The Gist:Absent another significant variant, experts are cautiously optimistic that enough of the US population will soon have either infection-acquired or vaccine-induced immunity that we may be nearing the end of the pandemic, and the beginning of “endemic COVID.”
The US must now shift from COVID “war footing” to learning how to live with the virus long term. That will mean tackling difficult and politically-charged decisions, such as what level of testing and masking are sustainable, and how many COVID deaths we are willing to tolerate.
The latest Omicron developments continue to be encouraging. New Covid-19 cases are plummeting in a growing list of places. The percentage of cases causing severe illness is much lower than it was with the Delta variant. And vaccines — particularly after a booster shot — remain extremely effective in preventing hospitalization and death.
I also think it’s time to begin considering what life after the Omicron wave might look like.
1. Plunging cases
Since early last week, new cases in Connecticut, Maryland, New Jersey and New York have fallen by more than 30 percent. They’re down by more than 10 percent in Colorado, Florida, Georgia, Massachusetts and Pennsylvania. In California, cases may have peaked.
“Let’s be clear on this — we are winning,” Mayor Eric Adams of New York said yesterday. Kathy Hochul, the governor of New York State, said during a budget speech, “We hope to close the books on this winter surge soon.”
If anything, the official Covid numbers probably understate the actual declines, because test results are often a few days behind reality.
The following data comes from Kinsa, a San Francisco company that tracks 2.5 million internet-connected thermometers across the country. It uses that data to estimate the percentage of Americans who have a fever every day. The declines over the past week have been sharp, which is a sign of Omicron’s retreat:
Many hospitals are still coping with a crushing number of patients, because Covid hospitalization trends often trail case trends by about a week. But even the hospital data shows glimmers of good news: The number of people hospitalized with Covid has begun declining over the past few days in places where Omicron arrived first:
The U.S. seems to be following a similar Omicron pattern as South Africa, Britain and several other countries: A rapid, enormous surge for about a month, followed by a rapid decline — first in cases, then hospitalizations and finally deaths.
Some of the clearest research on Covid’s risks comes from a team of British researchers led by Dr. Julia Hippisley-Cox of the University of Oxford. The team has created an online calculator that allows you to enter a person’s age, vaccination status, height and weight, as well as major Covid risk factors. (It’s based on an analysis of British patients, but its conclusions are relevant elsewhere.)
A typical 65-year-old American woman — to take one example — is five foot three inches tall and weighs 166 pounds. If she had been vaccinated and did not have a major Covid risk factor, like an organ transplant, her chance of dying after contracting Covid would be 1 in 872, according to the calculator. For a typical 65-year-old man, the risk would be 1 in 434.
Among 75-year-olds, the risk would be 1 in 264 for a typical woman and 1 in 133 for a typical man.
Those are meaningful risks. But they are not larger than many other risks older people face. In the 2019-20 flu season, about 1 out of every 138 Americans 65 and older who had flu symptoms died from them, according to the C.D.C.
And Omicron probably presents less risk than the British calculator suggests, because it uses data through the first half of 2021, when the dominant version of Covid was more severe than Omicron appears to be. One sign of Omicron’s relative mildness: Among vaccinated people in Utah (a state that publishes detailed data), the percentage of cases leading to hospitalization has been only about half as high in recent weeks as it was last summer.
For now, the available evidence suggests that Omicron is less threatening to a vaccinated person than a normal flu. Obviously, the Omicron wave has still been damaging, because the variant is so contagious that it has infected tens of millions of Americans in a matter of weeks. Small individual risks have added up to large societal damage.
3. Effective boosters
The final major piece of encouraging news involves booster shots: They are highly effective at preventing severe illness from Omicron. The protection is “remarkably high,” as Dr. Eric Topol of Scripps Research wrote.
Switzerland has begun reporting Covid deaths among three different groups of people: the unvaccinated; the vaccinated who have not received a booster shot; and the vaccinated who have been boosted (typically with a third shot). The first two shots still provide a lot of protection, but the booster makes a meaningful difference, as Edouard Mathieu and Max Roser of Our World in Data have noted:
The next stage
The Covid situation in the U.S. remains fairly grim, with overwhelmed hospitals and nearly 2,000 deaths a day. It’s likely to remain grim into early February. Caseloads are still high in many communities, and death trends typically lag case trends by three weeks.
But the full picture is less grim than the current moment.
Omicron appears to be in retreat, even if the official national data doesn’t yet reflect that reality. Omicron also appears to be mild in a vast majority of cases, especially for the vaccinated. This combination means that the U.S. may be only a few weeks away from the most encouraging Covid situation since early last summer, before the Delta variant emerged.
If that happens — and there is no guarantee it will, as Katherine Wu of The Atlantic explains — it will be time to ask how society can move back toward normalcy and reduce the harsh toll that pandemic isolation has inflicted, particularly on children and disproportionately on low-income children.
When should schools resume all activities? When should offices reopen? When should masks come off? When should asymptomatic people stop interrupting their lives because of a Covid exposure? Above all, when does Covid prevention do more harm — to physical and mental health — than good?
These are tricky questions, and they could often sound inappropriate during the Omicron surge. Now, though, the surge is receding.
The Omicron variant doesn’t cause as much severe illness as other variants have, but its “mild” symptoms can still be pretty unpleasant.
The big picture: The way health care professionals and doctors differentiate between “mild” and “severe” illness may not align with a layperson’s understanding of those terms.
“To a health care professional, ‘mild’ means you’re not getting hospitalized,” said Megan Ranney, academic dean at the Brown University School of Public Health.
But, she said: “Omicron symptoms can range from absolutely no symptoms to a really mild cold to something where you are in bed with shakes and chills, and have a horrible cough and are fatigued and headachy for weeks. Those are all ‘mild.'”
A “severe,” illness means you’d likely have symptoms such as very low oxygen levels, kidney damage and heart impairment, she said.
What we’re watching: Omicron is causing a lot less severe illness than previous variants, but a “mild” case can still require about a week away from work, especially in front-line jobs.
And because so many people have gotten infected in such a short time, it’s leaving schools, airlines, and other businesses — including, critically, hospitals — with large numbers of workers out sick simultaneously, The Atlantic reported.
Then there’s the matter of long COVID. A study published Thursday in Nature Immunology found ongoing, sustained inflammatory responses following even mild-to-moderate COVID-19 cases.
What they’re saying: “It’s going to be a messy few weeks. I don’t think there’s any way around it,” said Joseph Allen, a professor of public health at Harvard, per The Atlantic.
Even as daily new COVID cases set all-time records and hospitals fill up, epidemiologists have arrived at a perhaps surprising consensus. Yes, the latest Omicron variant of the novel coronavirus is bad. But it could have been a lot worse.
Even as cases have surged, deaths haven’t—at least not to the same degree. Omicron is highly transmissible but generally not as severe as some older variants—“lineages” is the scientific term.
We got lucky. But that luck might not hold. Many of the same epidemiologists who have breathed a sigh of relief over Omicron’s relatively low death rate are anticipating that the next lineage might be much worse.
Fretting over a possible future lineage that combines Omicron’s extreme transmissibility with the severity of, say, the previous Delta lineage, experts are beginning to embrace a new public health strategy that’s getting an early test run in Israel: a four-shot regimen of messenger-RNA vaccine.
“I think this will be the strategy going forward,” Edwin Michael, an epidemiologist at the Center for Global Health Infectious Disease Research at the University of South Florida, told The Daily Beast.
Omicron raised alarms in health agencies all over the world in late November after officials in South Africa reported the first cases. Compared to older lineages, Omicron features around 50 key mutations, some 30 of which are on the spike protein that helps the virus to grab onto our cells.
Some of the mutations are associated with a virus’s ability to dodge antibodies and thus partially evade vaccines. Others are associated with higher transmissibility. The lineage’s genetic makeup pointed to a huge spike in infections in the unvaccinated as well as an increase in milder “breakthrough” infections in the vaccinated.
That’s exactly what happened. Health officials registered more than 10 million new COVID cases the first week of January. That’s nearly double the previous worst week for new infections, back in May. Around 3 million of those infections were in the United States, where Omicron coincided with the Thanksgiving, Christmas, and New Year holidays and associated traveling and family gatherings.
But mercifully, deaths haven’t increased as much as cases have. Worldwide, there were 43,000 COVID deaths the first week of January—fewer than 10,000 of them in the U.S. While deaths tend to lag infections by a couple weeks, Omicron has been dominant long enough that it’s increasingly evident there’s been what statisticians call a “decoupling” of cases and fatalities.
“We can say we dodged a bullet in that Omicron does not appear to cause as serious of a disease,” Stephanie James, the head of a COVID testing lab at Regis University in Colorado, told The Daily Beast. She stressed that data is still being gathered, so we can’t be certain yet that the apparent decoupling is real.
Assuming the decoupling is happening, experts attribute it to two factors. First, Omicron tends to infect the throat without necessarily descending to the lungs, where the potential for lasting or fatal damage is much, much higher. Second, by now, countries have administered nearly 9.3 billion doses of vaccine—enough for a majority of the world’s population to have received at least one dose.
In the United States, 73 percent of people have gotten at least one dose. Sixty-two percent have gotten two doses of the best mRNA vaccines. A third have received a booster dose.
Yes, Omicron has some ability to evade antibodies, meaning the vaccines are somewhat less effective against this lineage than they are against Delta and other older lineages. But even when a vaccine doesn’t prevent an infection, it usually greatly reduces its severity.
For many vaccinated people who’ve caught Omicron, the resulting COVID infection is mild. “A common cold or some sniffles in a fully vaxxed and boosted healthy individual,” is how Eric Bortz, a University of Alaska-Anchorage virologist and public health expert, described it to The Daily Beast.
All that is to say, Omicron could have been a lot worse. Viruses evolve to survive. That can mean greater transmissibility, antibody-evasion or more serious infection. Omicron mutated for the former two. There’s a chance some future Sigma or Upsilon lineage could do all three.
When it comes to viral mutations, “extreme events can occur at a non-negligible rate, or probability, and can lead to large consequences,” Michael said. Imagine a lineage that’s as transmissible as Omicron but also attacks the lungs like Delta tends to do. Now imagine that this hypothetical lineage is even more adept than Omicron at evading the vaccines.
That would be the nightmare lineage. And it’s entirely conceivable it’s in our future. There are enough vaccine holdouts, such as the roughly 50 million Americans who say they’ll never get jabbed, that the SARS-CoV-2 pathogen should have ample opportunities for mutation.
“As long as we have unvaccinated people in this country—and across the globe—there is the potential for new and possibly more concerning viral variants to arise,” Aimee Bernard, a University of Colorado immunologist, told The Daily Beast.
Worse, this ongoing viral evolution is happening against a backdrop of waning immunity. Antibodies, whether vaccine-induced or naturally occurring from past infection, fade over time. It’s not for no reason that health agencies in many countries urge booster doses just three months after initial vaccination. The U.S. Centers for Disease Control and Prevention is an outlier, and recommends people get boosted after five months.
A lineage much worse than Omicron could evolve at the same time that antibodies wane in billions of people all over the world. That’s why many experts believe the COVID vaccines will end up being annual or even semi-annual jabs. You’ll need a fourth jab, a fifth jab, a sixth jab, et cetera, forever.
Israel, a world leader in global health, is already turning that expectation into policy. Citing multiple studies that showed a big boost in antibodies with an additional dose of mRNA and no safety concerns, the country’s health ministry this week began offering a fourth dose to anyone over the age of 60, who tend to be more vulnerable to COVID than younger people.
That should be the standard everywhere, Ali Mokdad, a professor of health metrics sciences at the University of Washington Institute for Health, told The Daily Beast. “Scientifically, they’re right,” he said of the Israeli health officials.
If there’s a downside, it’s that there are still a few poorer countries—in Africa, mostly—where many people still struggle to get access to any vaccine, let alone boosters and fourth doses. If and when other richer countries follow Israel’s lead and begin offering additional jabs, there’s some risk of even greater inequity in global vaccine distribution.
“The downside is for the rest of the world,” Mokdad said. “I’m waiting to get my first dose and you guys are getting a fourth?”
The solution isn’t to deprive people of the doses they need to maintain their protection against future—and potentially more dangerous—lineages. The solution, for vaccine-producing countries, is to further boost production and double down on efforts to push vaccines out to the least privileged communities.
A sense of urgency is key. For all its rapid spread, Omicron has actually gone fairly easy on us. Sigma or Upsilon might not.
