Pfizers Covid-19 vaccine is 92% effective at preventing serious illness, Israeli study says – The Times

Ninety-two per cent of recipients of the Pfizer vaccine have been protected from developing severe symptoms of Covid-19, the most comprehensive study of the jab has found.

The study, published in The New England Journal of Medicine, was based on medical data from 1.2 million patients of Israel’s largest healthcare provider, half of whom were vaccinated by the Pfizer-BioNTech vaccine. It was conducted by a team of doctors and researchers led by Professor Ran Balicer of Israel’s Clalit Health Services, along with a team of senior researchers from Harvard University, and is the largest study of its kind to date.

The research found that on average the vaccine prevents 94 per cent of people developing symptoms; 92 per cent did not develop serious illness.
