U.S. regulators told COVID-19 vaccine makers Thursday that any booster shots tweaked for the fall will have to add protection against the newest omicron relatives.
FILE - A Northwell Health registered nurse fills a syringe with a COVID-19 vaccine at a pop up vaccination site the Albanian Islamic Cultural Center, April 8, 2021, in the Staten Island borough of New York. The Food and Drug Administration on Thursday, June 30, 2022 recommended that COVID-19 booster shots be modified to better match more recent variants of the coronavirus.
It's still a gamble as there's no way to know if an omicron relative still will be a threat as cold weather approaches or if a newer mutant will take its place. And the current Pfizer and Moderna vaccines still offer strong protection against COVID-19's worst outcomes as long as people have gotten already recommended boosters.
“We’re continuing to collect more data from our study on BA.4/5 and will be in touch as soon as we are ready to submit,” Pfizer spokeswoman Jerica Pitts said in an emailed message. The FDA’s order doesn’t guarantee that those combo shots would be offered in the fall. Manufacturers still have to provide key data before the agency decides whether to authorize modified boosters -- and the Centers for Disease Control and Prevention then would have to decide how they’re used.
