1/ Johnson and Johnson’s single-dose Covid-19 vaccine was 66% effective overall at preventing moderate to severe illness in a global study. In the U.S., the vaccine was 72% effective, but the efficacy rate dropped to 57% in South Africa, where a highly contagious variant is driving new cases. The vaccine was particularly effective at stopping severe disease in all regions, preventing 85% of severe infections and 100% of hospitalizations and deaths. Johnson and Johnson said it planned to apply for emergency authorization of its vaccine from the FDA, putting it on track to receive clearance later in February.
