(HealthDay News) — Americans could be getting updated COVID-19 booster shots that can battle the newest omicron variants as soon as mid-September.
People close to deliberations say that the Biden administration plans to offer a booster campaign with new formulations because the makers of the primary vaccines used in the United States, Pfizer and Moderna, have said they can deliver the new doses by then, The New York Times reported. This could mean that younger Americans not yet eligible for a second booster of the original vaccines will have to wait until the fall for shots.
Some in the administration have said that use of the original boosters should be expanded now, as highly contagious omicron variants spread, while others say the better option is to strengthen everyone’s immunity in the fall with a booster that can tackle the BA.5 variant before a potential winter surge.
Despite the debate, the federal government plans to continue recommending that people who are eligible for a second booster get it now and not wait for the fall shot. Some are concerned that people do not get their booster doses too close together, in part because the second may not work as well in close succession to the first. Another concern was that 2 shots too close together might increase the risk for myocarditis.
There is also worry that the public may grow weary of multiple shots, as evidenced by the fact that there is less uptake of shots with each dose. Nearly half of eligible people got a first booster, but only 30% have received their second booster, data from the US Centers for Disease Control and Prevention show.
The Biden administration is working on contracts for the reformulated booster doses, with the U.S. Department of Health and Human Services making a $3.2 billion advance purchase of 105 million doses made by Pfizer, The Times reported. A similar agreement is expected with Moderna. All adults and possibly children could be eligible for the new boosters.
