What to know about a 2nd COVID-19 booster for people over age 50
ABC News
Experts reveal what you need to know about the FDA's reported plan to authorize a second COVID booster shot for those aged 50 and older.
Another COVID-19 vaccine booster shot may be on the horizon for Americans, as the U.S. Food and Drug Administration is expected to greenlight a fourth dose for those aged 50 and older as soon as Tuesday.
It comes after Pfizer-BioNTech requested the FDA authorize a fourth dose for Americans aged 65 and older earlier this month and Moderna asked the same, but for those aged 18 and older.
Several other countries have already begun administering a second booster, and the Centers for Disease Control and Prevention currently recommends immunocompromised Americans receive a fourth dose.
Two officials familiar with the matter told ABC News the fourth shots will likely be only offered and not formally recommended.
