Pfizer and BioNTech said Wednesday that the final analysis of its coronavirus vaccine was 95% effective in late stage trials — and it caused no serious concerns.

What’s going on?

Pfizer counted 170 cases of coronavirus infection among volunteers who participated in the trial stage.

  • The company said there were 162 infections for those who got the placebo, or plain saline shots, while there were eight for those who got the vaccine.
  • Pfizer said that means there’s a 95% efficacy rate.
  • Pfizer said there were also 10 severe cases of COVID-19 in the trial. Nine cases came from the placebo group and only one came from the vaccinated group.
  • The name of the vaccine is BNT162b2.
