The Centers for Disease Control and Prevention Director Dr. Rochelle Walensky signed off on newly-updated COVID-19 booster shots Thursday night, giving the final clearance shots to be administered soon after.
The new booster shots have been updated to target two different COVID strains in one shot -- the current omicron subvariants, BA.4 and BA.5, which make up 99% of new cases in the U.S., and the original strain of COVID-19.
This is the first time current COVID-19 vaccines have had a major upgrade. In the future, experts expect the vaccines could be updated periodically to match current strains -- akin to the way the flu shot is slightly different each year.
Walensky urged eligible Americans to get the shot.
