Pfizer, BioNTech Filing Planned as Vaccine Proves 95% Effective
Updated on

Pfizer Inc. said a final analysis of clinical-trial data showed its Covid-19 vaccine was 95% effective, paving the way for the company to apply this week for the first U.S. regulatory authorization for a coronavirus shot.

The U.S. drugmaker and partner BioNTech SE said their vaccine protected people of all ages and ethnicities, with no significant safety problems so far in a trial that includes almost 44,000 participants.
