The questions we must ask about the Covid vaccine

After a difficult nine months, we are naturally all sick of lockdowns and other Covid restrictions. Everyone misses parts of their pre-coronavirus lives, from seeing friends and family, to pubs and restaurants, to the theatre and concerts and, yes, even our workplaces. It was therefore no surprise that this week’s news of a vaccine breakthrough was widely applauded. It is human nature, after all, to cling on to things that give us hope. Hope that was encouraged by leading scientists such as Sir John Bell. After the Pfizer news broke, the Oxford professor was asked on BBC radio whether we would be returning to normal by spring. His response? ‘Yes, yes, yes.’ This was a When Harry Met Sally moment that proved to be music to the ears of millions of Britons.

However, as a microbiologist who has worked on vaccine discovery, I struggle to see how, despite this very welcome leap, we can possibly be back to normal by spring.
