Pfizer says new data shows healthy 5- to 11-year-olds could benefit from another kid-sized shot.
U.S. health authorities already urge everyone 12 and older to get one booster dose for the best protection against the newest variants — and recently gave the option of a second booster to those 50 and older.In a small study, 140 youngsters who'd already gotten two shots were given a booster six months later, and researchers found the extra shot generally revved up their immune response.
Vaccinations are generally less effective against the omicron variant than earlier versions of the coronavirus — but they do still offer strong protection against severe disease. While COVID-19 is a bigger threat to adults, youngsters can get seriously ill. But regulators will have to decide if healthy elementary-age kids really need a booster, and if so, when.
The U.S. hasn't yet allowed vaccinations for children under 5. But certain 5- to 11-year-olds — those with severely weakened immune systems — already are supposed to get three doses, to give that high-risk group a better chance of responding.
