Pfizer and BioNTech say final analysis shows coronavirus vaccine is 95% effective with no safety concerns

A final analysis of the Phase 3 trial of Pfizer’s coronavirus vaccine shows it was 95% effective in preventing infections, even in older adults, and caused no serious safety concerns, the company said Wednesday.
