If you’re looking for recent reasons to be proud of Britain, it would be hard to find a better example than the Recovery series of clinical trials. Conceived in haste in the early days of the pandemic, Recovery (which stands for Randomised Evaluation of Covid-19 Therapy) sought to find drugs to help treat people seriously ill with the novel disease. It brought together epidemiologists, statisticians and health workers to test a range of promising existing drugs at massive scale across the NHS.
The secret of Recovery’s success is that it was a series of large, fast, randomised experiments, designed to be as easy as possible for doctors and nurses to administer in the midst of a medical emergency. And it worked wonders: within three months, it had demonstrated that dexamethasone, a cheap and widely available steroid, reduced Covid deaths by a fifth to a third. In the months that followed, Recovery identified four more effective drugs, and along the way showed that various popular treatments, including hydroxychloroquine, President Trump’s tonic of choice, were useless. All in all, it is thought that Recovery saved a million lives around the world, and it’s still going.
