AstraZeneca COVID vaccine 76% effective in new US trial analysis | Al Jazeera

AstraZeneca said its COVID-19 vaccine was 76 percent effective at preventing symptomatic illness in a new analysis of its key trial in the United States – slightly lower than the level announced earlier this week in a report that was criticised for using outdated information.
US health officials had publicly rebuked the drugmaker for not using the most up-to-date information when it published an interim analysis on Monday that said the vaccine was 79 percent effective.
