A 90-year-old woman named Margaret Keenan has become the first person in the world to receive the Pfizer COVID-19 vaccine in United Kingdom (UK). She has received the vaccine from nurse May Parsons who has worked in the National Health Service (NHS).
Earlier, the UK had authorized Pfizer-BioNTech COVID-19 vaccine to be made available across the country. Pfizer and its German partner BioNTech said had said in November that the shot, relying on novel technology called messenger RNA, was 95% effective in a final analysis of clinical-trial data.
