U.S. regulators on Tuesday authorized a COVID-19 booster shot for healthy 5- to 11-year-olds, hoping an extra vaccine dose will enhance their protection as infections once again creep upward.
There is one more hurdle: The Centers for Disease Control and Prevention must decide whether to formally recommend the booster for this age group. The CDC’s scientific advisers are scheduled to meet on Thursday.
Whether elementary-age children need a booster has been overshadowed by parents’ outcry to vaccinate even younger tots, those under 5 -- the only group not yet eligible in the U.S. Both Pfizer and rival Moderna have been studying their shots in the youngest children, and the FDA is expected to evaluate data from one or both companies sometime next month.
But in a small study, Pfizer found a booster revved up those kids’ levels of virus-fighting antibodies -- including those able to fight omicron -- the same kind of jump adults get from an extra shot. Adding to public confusion, the CDC estimates 3 out of every 4 U.S. children of all ages have been infected with the coronavirus since the pandemic’s start -- many of them during the winter omicron wave. Still, health authorities urge vaccination even in people who’ve previously had COVID-19, to strengthen their protection.
