FDA simplifies COVID vaccine schedules, withdraws authorization for older COVID-19 vaccines targeting virus’ original strain
ABC News (4/18/23) – The Food and Drug Administration authorized a second omicron-targeted bivalent COVID-19 booster vaccine for people over 65 or who are immunocompromised, the agency announced Tuesday.
The agency also said any adult who has not yet been vaccinated will get one dose of an updated bivalent shot, rather than starting with the original vaccine and receiving the bivalent shot as a booster. The FDA is withdrawing authorization for those older COVID-19 vaccines targeting the original strain of the virus.
