COVID-19 vaccines designed to target the omicron variant have just been authorized by the Food and Drug Administration. Both Pfizer / BioNTech and Moderna got the FDA’s sign-off for their booster doses of the reformulated shot. This is the first update to COVID-19 vaccines to be authorized in the United States.
The Pfizer / BioNTech booster is available to people 12 and older, and the Moderna shot will be available to people 18 and older. They’ll only be boosters — they can’t be used by people who haven’t already had their first doses.
