Recovery trial for Covid-19 treatments: what we know so far

Recovery, based at Oxford University, is the biggest randomised controlled trial of drugs against Covid-19 in the world, thanks in no small part to the NHS. The trial has been testing six different treatments against the normal standard of care – which in Covid-19 means mostly oxygen support. Following the breakthrough with dexamethasone, the NHS made it clear that the drug would be madeavailable toall patientswho might be helped by it. This is from blood donated by patients who have recovered from Covid-19 and will contain antibodies that their immune systems have generated against the virus.
