It’s day one of the lockdown in England, and it’s been a turbulent week in US politics. Thankfully Robin McKie, the Observer’s science editor, has some good news on the race to find a vaccine
The Observer’s science editor, Robin McKie, talks to Anushka Asthana about the race to find a Covid-19 vaccine. A total of 198 Covid vaccines are under development worldwide, with four key versions undergoing final phase 3 trials. These include Pfizer’s BNT162b2 and the Oxford AstraZeneca vaccine. Results of those trials – in which each is compared with a placebo – are expected in weeks or months.
A vaccine that works is seen as a game-changer in the battle against coronavirus, which has killed more than 1.15 million people, shuttered swathes of the global economy and turned normal life upside down for billions of people. However, few think the first vaccines will be fully protective. They may instead reduce the severity of illness, so people avoid hospital and deaths are reduced.
