UK began rolling out the COVID-19 vaccine developed by Pfizer and BioNTech today. Margaret Keenan, a 90-year-old grandmother, has become the first person in the world to receive the Pfizer Covid-19 vaccine outside of a trial following its rapid clinical approval. "I feel so privileged to be the first person vaccinated against Covid-19," said Keenan as reported by Reuters.

"It's the best early birthday present I could wish for because it means I can finally look forward to spending time with my family and friends in the New Year after being on my own for most of the year."

Margaret Keenan, the former jewellery shop assistant, received the shot at University Hospital Coventry at 6:31 a.m. while wearing a surgical mask.
