Los Angeles County health officials and other providers began offering second booster doses of the COVID-19 vaccine to residents 50 older on March 30.

This action comes after the U.S. Food and Drug Administration (FDA) authorized a second booster dose of either the Pfizer-BioNTech or the Moderna COVID-19 vaccines for older and immunocompromised individuals on Tuesday.
