How Realistic Is Biden’s Call for Annual COVID Booster Shot?

In October, when President Joe Biden rolled up his sleeve to get the improved COVID-19 booster, he guaranteed that most Americans would only require one coronavirus shot per year.  

Biden stated at the White House, “For the majority of Americans, an annual COVID vaccination will be sufficient.” “And if you obtain it, you will be safeguarded. And if you don’t, you put yourself and others in unnecessary danger.”  

He has also disseminated the notion via Twitter, stating, “According to our nation’s specialists, the majority of people will only require one updated COVID vaccine to be protected for the entire year. One vaccination per year. Just like flu.” As per US News, the statement has been echoed by Biden’s senior health experts.  

In September, leading infectious disease expert Anthony Fauci stated, “It is becoming increasingly apparent that, going forward with the COVID-19 pandemic, in the absence of a dramatically different variant, we are likely moving toward a path with a vaccination cadence similar to that of the annual influenza vaccine, with annual updated COVID-19 shots matched to the currently circulating strains for the majority of the population.”  

However, more than three months after the Biden administration originally floated the notion of an annual COVID-19 booster shot, no official policy has been announced due to the existence of outstanding questions and obstacles.  

For starters, the ever-changing pool of COVID-19 variations makes it impossible to formulate a shot that precisely matches what is circulating – a difficulty similar to that encountered each flu season by the influenza vaccine. The improved bivalent vaccines were created to protect against omicron subvariants BA.4 and BA.5, in addition to the original coronavirus strain. Since the images were released at the end of August, the alternative scene has inevitably shifted.  

According to estimates from the Centers for Disease Control and Prevention, XBB.1.5 caused almost 40 percent of COVID-19 infections in the U.S. last week, whereas BA.5 was the predominant strain in August. It has been described as the “most transmissible subtype yet found,” and it is unknown how well the new booster shot will protect against it.  

The majority of XBB.1.5 infections are caused by omicron subvariants. Therefore, although public health officials believe the updated boosters will still provide increased protection against severe disease, hospitalization, and death from XBB.1.5, the shots are not a perfect match to the omicron subvariants that are responsible for the majority of infections.  


It is a sobering reminder of how rapidly the alternative culture may evolve. The Biden administration has admitted that the emergence of a new COVID-19 variant is one of the most significant drawbacks of switching to a yearly booster cycle. Fauci stated that if an improbable, out-of-the-blue variety materializes, all bets are off, and the annual booster notion will be altered.  

However, variations are not the only concern with this method. Additionally, the Biden administration would have to determine the best time of year to offer the vaccine, which could be difficult.  

Officials from the administration have compared the COVID-19 booster campaign to the flu shot, which is suggested in the fall to maximize protection during the winter flu season. However, the coronavirus has not yet become seasonal, with peaks occurring in the summer, fall, and winter.  

Keri Althoff, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, explains, “We know that the vaccination is protective, but it’s most effective shortly after it’s provided, so it’s best to get it before there’s a lot of transmission in your neighborhood.”  

The issue is that the antibodies created by the COVID-19 vaccinations diminish with time, with earlier research indicating a significant reduction within the first three months. However, circumstances vary from individual to individual, and protection against serious sickness tends to outlast protection against infection.  

“When discussing declining antibodies, it is important to realize that this is not a switch,” explains Althoff. It does not mean that after six months, you are suddenly no longer protected by a vaccine. In addition, experts concur that administering a booster shot every three to four months, as the antibodies from the preceding shot wane, is not the solution.  

“Will we be in a position to prescribe a vaccine every three or four months simply because antibodies are waning? No”, adds Althoff, “but if we see an annual vaccine for COVID, we will certainly need to consider the scheduling of it to ensure the best degree of protection during the times when we anticipate the highest levels of transmission in our communities.”  

In late January, a team of vaccination specialists will debate precisely these issues at an upcoming Food and Drug Administration conference. They will discuss, among other things, “how and whether the composition and timetable for booster doses should be altered in the future.”  

“Since the first authorizations of these vaccinations, we have learned that protection wanes over time, particularly when the virus quickly mutates and new variations and subvariants develop,” FDA’s Peter Marks said in a Jan. 26 statement announcing the meeting. Therefore, it is essential to continue discussing the appropriate composition of COVID-19 vaccines for main and booster immunization, as well as the optimal booster vaccination interval.  

Marks stated that he is “hopeful that this future conversation will provide us with the appropriate road forward for COVID-19 vaccines, ensuring that the public stays optimally protected against changing virus strains.”  

However, the agency’s external experts confront a formidable challenge, as the Biden administration has already publicized its intention to launch an annual COVID-19 promotion campaign. This public goal could impede the agency’s capacity to conduct an objective discussion regarding the optimal immunization schedule.  

The Biden administration is in a difficult position, according to William Schaffner of the Vanderbilt University Medical Center, since it “has to steer the people in a direction that gives them a sense of where we’re going and where we’re headed.”  

He says, “I sympathize with political leaders since they are in a precarious position.” “I’d always hope they’d say, ‘I hope we’re headed in this direction, but we haven’t decided yet'” If the campaign for the revised boosters served as a test for the future changeover to annual vaccinations, public health officials will certainly face an uphill battle against vaccine fatigue.  

According to CDC data, approximately 15% of Americans over the age of 4 have received the vaccination – a far lower percentage than experts had anticipated for when the vaccinations became legal in late August.  

Schaffner states, “The vaccine has not been received as extensively or enthusiastically as any of us in infectious diseases and public health had predicted, hoped for, or anticipated.” Schaffner explains, “This season has been especially difficult since we’ve encouraged individuals to obtain not just one vaccine, but two: the new COVID booster as well as the normal seasonal influenza vaccine.” And we are not nearly as successful as we would like in the uptake of these two vaccines.  

However, he is optimistic that efforts to combine the COVID-19 vaccine with influenza vaccination could alleviate the uptake issue. Naturally, that would be much more acceptable to the general public than requiring two doses, Schaffner explains.
