AstraZeneca on Thursday published an updated analysis confirming that a Phase 3 trial involving its COVID-19 vaccine was safe and effective, and showed to be 76% effective against symptomatic COVID-19.
The earlier data reflected 79% efficacy in preventing symptomatic infections and 100% efficacy at preventing severe disease and hospitalization. The new analysis also reported 100% efficacy "against severe or critical disease and hospitalization." "Positive high-level results from the primary analysis of the Phase III trial of AZD1222 in the U.S. have confirmed vaccine efficacy consistent with the pre-specified interim analysis announced on Monday 22 March 2021," a press release posted by AstraZeneca early Thursday stated. "These results have been presented to the independent Data Safety Monitoring Board. The primary analysis is pre-specificed in the protocol and will be the basis for a regulatory submission for Emergency Use Authorization to the U.S. Food and Drug Administration in the coming weeks."More Related News
