FDA says J&J 1-dose shot prevents COVID; final decision soon

Johnson & Johnson’s single-dose vaccine protects against COVID-19, according to an analysis by US regulators today 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 confirm that overall the vaccine is about 66% effective at preventing moderate to severe COVID-19. The agency also says J&J’s shot — one that could help speed vaccinations by requiring just one dose instead of two — is safe to use.

That’s just one step in the FDA’s evaluation of a third vaccine option for the US On Friday, the agency’s independent advisers will debate if the evidence is strong enough to recommend the long-anticipated shot. Armed with that advice, FDA is expected to make a final decision within days.
