Sir John Bell: ‘Most people who have had the Covid vaccine are completely safe’

The renowned immunologist remains as upbeat about jabs - and UK life science - as he was in the depths of the pandemic

Sir John Bell, the Canadian immunologist, is a familiar sight to locals along the stretch of the Thames near his home in Wallingford, just outside Oxford, where he and his wife can often be seen rowing in a double scull.

During the pandemic, Bell's voice became familiar to millions of radio listeners too. As news broke that a viable Covid-19 vaccine was on its way, following successful trials by Pfizer and BioNTech, Bell was asked on BBC Radio 4 whether the world would now return to normal. His response was an emphatic yes, yes, yes". His words not only lifted spirits: they moved markets.
