AstraZeneca’s latest data analysis affirms effectiveness of its COVID-19 vaccine and is roughly in line with the results released Monday.
The latest analysis finds the vaccine to be 76% effective against symptomatic COVID-19 and 100% effective against severe or critical disease and hospitalization. These results are very close to the results that came out at the beginning of the week: 79% vaccine efficacy at preventing symptomatic COVID-19 and 100% effective against severe or critical disease and hospitalization.
An independent monitoring board raised questions about the company’s release Monday, saying it didn’t include more up-to-date cases that were available. The updated analysis includes 49 more cases of COVID-19 than the Monday analysis.
