'I'm so happy': first person to get fully-tested COVID-19 shot says one year on

The first person in the world to be given a fully-tested COVID-19 vaccine, 91-year-old Briton Margaret Keenan, urged people on Wednesday to get vaccinated, one year on from her shot. Keenan described receiving the Pfizer-BioNTech COVID-19 vaccine on Dec. 8 2020 as the 'best thing that has ever happened'. 'It was wonderful. I cannot believe it now, what happened at the time... I'm so happy I got the jab,' Keenan, known to friends as Maggie, said in a broadcast clip to mark the anniversary.
