UK becomes first Western country to approve a coronavirus vaccine

The United Kingdom has granted emergency authorization to Pfizer’s coronavirus vaccine, becoming the first Western country to approve a vaccine to prevent COVID-19. The first doses of the vaccine are expected to roll out in the U.K. next week.

Prizer’s coronavirus vaccine, developed with BioNTech, was recently shown to be 95% effective in preventing COVID-19 among participants of a still-ongoing late-stage clinical trial, Live Science previously reported. The vaccine uses messenger RNA, a type of genetic material that teaches the body to recognize a key protein of the virus and attack it. Pfizer’s vaccine also seems to reduce the incidence of severe disease (One out of 10 severe cases in the trial was in a participant who received the vaccine.)
