1. AstraZeneca says updated analysis found COVID-19 vaccine 76 percent effective

AstraZeneca on Wednesday released an analysis with updated data that found its coronavirus vaccine was 76 percent effective in preventing symptomatic COVID-19, down slightly from the initial claim of 79 percent effectiveness. It is 100 percent effective at averting severe illness and hospitalization. Days earlier, government scientists said AstraZeneca had cherry-picked data from a predominantly U.S. study of 32,000 people, relying on "incomplete information" to come up with the initial estimate of its effectiveness. Dr. Anthony Fauci, the top U.S. infectious disease expert, said Wednesday before AstraZeneca released its update that the controversy was an "unforced error," but he was confident that when all the data was vetted it would "turn out to be a good vaccine."
