AstraZeneca released primary analysis showing that the company’s AZD1222 vaccine demonstrated 76 percent efficacy against symptomatic Covid-19, 100 percent efficacy against severe or critical disease and hospitalizations, and 85 percent efficacy against symptomatic Covid-19 in people 65 years and older.

The first big real-world study of the Pfizer/BioNTech vaccine to be independently reviewed shows the shot is highly effective at preventing Covid-19, in a potentially landmark moment for countries desperate to end lockdowns and reopen economies.

Israel’s largest healthcare provider reported a 94% drop in symptomatic Covid-19 infections among 600,000 people who received two doses of Pfizer’s vaccine in the country’s biggest study to date.
