FDA set to approve third vaccine dose for immunocompromised

The Food and Drug Administration is expected to authorize third shots of the COVID-19 vaccines for people with compromised immune systems this week, reports said.

The move would come amid a surge in cases due to the more contagious Delta variant. The FDA will amend the emergency use authorizations for the two-dose Pfizer and Moderna vaccines – but not the one-and-done Johnson & Johnson vaccine, NBC News reported, citing sources.
