A vaccine for Covid-19 could soon be within grasp as British scientists kick off the world’s biggest human trial.
Up to 400 people have volunteered for the project, which is led by Oxford University and will test four drugs.
They include the anti-malaria drug hydroxychloroquine, an anti-inflammatory drug, a steroid and an anti-retroviral drug that is normally used to treat HIV.
The Recovery trial, which takes in 150 UK hospitals, will kick off within days and is due to wrap up in August.
Similar trials under way in the US and Europe have a few hundred patients in total.
Key Government adviser Sir John Bell, who is part of our vaccine taskforce, said: “If we can see evidence of a strong immune response by the middle or the end of May, then I think the game is on.
“Then, of course, there is the massive issue of how you manufacture at scale many billions of doses.”
