FILE - A health worker administers a dose of a Pfizer COVID-19 vaccine during a vaccination clinic in Reading, Pa., Sept. 14, 2021. Pfizer asked U.S. regulators Monday, Aug. 22, 2022, to authorize its combination COVID-19 vaccine that adds protection against the newest omicron mutants a key step toward opening a fall booster campaign.
If the FDA quickly clears the combo shots made by Pfizer and its partner BioNTech, boosters could be offered within weeks. The U.S. has a contract to buy 105 million of the updated Pfizer doses as soon as health authorities greenlight them, and the company said doses are ready to ship. “It’s going to be really important that people this fall and winter get the new shots. It’s designed for the virus that’s out there,” White House COVID-19 coordinator Dr. Ashish Jha said last week.For now at least. BA.5 currently is causing nearly all COVID-19 infections in the U.S., and much of the world. There’s no way to know if it still will be a threat this winter -- or if another mutant will have replaced it.
