U.K. medical teams began administering Pfizer-BioNTech coronavirus vaccine doses on Tuesday, with people aged 80 and older the first to be inoculated.
The big picture: The U.K. last week became the first Western nation to give emergency approval for a COVID-19 vaccine. Margaret Keenan, 90, was the world's first person to get a fully tested, clinically authorized COVID-19 vaccine, at a hospital in Coventry, England. Health Secretary Matt Hancock said, "We will look back on today, V-day, as a key moment in our fightback against this terrible disease."
Margaret Keenan, a 90-year-old grandmother, received the first dose of the Pfizer/BioNTech vaccine at 6.31am this morning from nurse May Parsons in Coventry.
