ON Dec 8 last year, Margaret Keenan became the first person in the United Kingdom to receive a Covid-19 vaccine. She took her second dose three weeks later, having celebrated her 91st birthday in between the shots.
Her vaccination marked the start of the largest inoculation exercise the UK has ever seen in modern times. Fast forward some eight months later, 88% of the population have received their first dose and 66.8% are fully vaccinated as of July 19, the day the government of Boris Johnson lifted all the coronavirus restrictions in England.
