Britain has vaccinated its first citizen against the COVID-19 virus. Ninety-year-old nursing home resident Margaret Keenan received the first of two doses of a vaccine jointly developed by U.S.-based pharmaceutical giant Pfizer and Germany’s BioNTech.
The vaccination campaign, dubbed “V-Day” by Health Secretary Mark Hancock, began nearly a week after the government’s medical regulatory agency granted emergency approval for the vaccine, making Britain the first western nation ready to begin mass inoculations.
