If one clear lesson is to be taken from our response to the arrival of Covid-19 three years ago, it is an appreciation of the highly effective role played by scientists in fighting the pandemic. Within weeks of the Sars-CoV-2 virus emerging, researchers had sequenced every one of its genes and had pinpointed the cells through which Covid-19 enters the body. By the end of the year, they had used that knowledge to create a safe, tested vaccine that played a crucial role in ending the pandemic. More than 7 million people across the planet have died of Covid-19 but the death toll would have been far higher had researchers not acted with such speed and potency.
Yet it is also becoming clear that on many occasions scientists were not listened to by national leaders. Economics and short-term political considerations were often given greater priority than scientific concerns. These resulted in failures to limit the spread of Covid-19. It is for this reason that the UK inquiry into the nation’s pandemic response, chaired by Heather Hallett, should be followed with rigorous attention.
