FDA clears second bivalent COVID-19 booster in older adults, immunocompromised patients

The Washington Post (4/18, McGinley, Sun) reports that the FDA “cleared the way for people who are at least 65 years old or immune-compromised to receive a second updated booster shot against the coronavirus, an option designed to bolster protection for the most vulnerable Americans even as the pandemic recedes.” This “bivalent booster…targets Omicron subvariants BA.4 and BA.5 as well as the original coronavirus.” Although “BA.4 and BA.5 have largely disappeared, the shot works on other Omicron subvariants that have become widespread, officials say.”
