I saw this today on the Washington Post – FDA authorizes Pfizer-BioNTech coronavirus vaccine booster for older Americans and those at high risk of illness: https://www.washingtonpost.com/health/2021/09/22/pfizer-booster-shot-fda-authorizes/. Longer article.
The Food and Drug Administration on Wednesday authorized a Pfizer-BioNTech coronavirus booster shot for people 65 and older and adults at risk of severe illness, an effort to bolster protection for the most vulnerable Americans against the highly transmissible delta variant of the virus.
In addition to older Americans, boosters should be made available to people 18 through 64 years of age at high risk of severe illness from the coronavirus and those “whose frequent institutional or occupational exposure” to the virus puts them at high risk of serious complications from the disease caused by the virus, the agency said.
The agency said the extra dose of the Pfizer-BioNTech vaccine should be administered six months after its standard two-shot regimen.
