An analysis of Johnson & Johnson's single-dose vaccine shows it does protect against COVID-19. On Wednesday U.S. regulators involved in the analysis of the drug made the announcement. The hope is the single-dose shot will help in the fight against the pandemic.
The Food and Drug Administration says Johnson & Johnson's shot could help speed up vaccinations by requiring just one dose instead of two. FDA scientists say the vaccine is about 66% effective at preventing moderate to severe COVID-19.
Johnson & Johnson hoped to deliver 10 million doses of its vaccine by the end of February. The company has come out saying it will fall short of that goal and is now promising to deliver another 20 million by the end of March.
This is the third company to request authorization of a COVID-19 vaccine. The FDA is expected to make its decision in the coming days.
