Pfizer To Seek FDA OK For COVID-19 Vaccine 'Within Days'

Pfizer is ready to ask the Food and Drug Administration to authorize emergency use of the company's COVID-19 vaccine, after an updated analysis of the clinical trial data found the vaccine to be 95% effective.

The results from the final efficacy analysis of the vaccine study were released Wednesday. An interim analysis released Nov. 9 had indicated the vaccine was more than 90% effective.

In the Phase 3 study involving more than 43,000 volunteers, half received the experimental vaccine and half got a placebo. Participants received two shots, spaced 21 days apart.
