WASHINGTON (AP) — Johnson & Johnson’s single-dose vaccine protects against COVID-19, according to an analysis by U.S. regulators Wednesday that sets the stage for a final decision on a new and easier-to-use shot to help tame the pandemic.

The Food and Drug Administration’s scientists confirmed that overall the vaccine is about 66% effective at preventing moderate to severe COVID-19. The agency also said J&J’s shot — one that could help speed vaccinations by requiring just one dose instead of two — is safe to use.
