(Wired) – The drug hydroxychloroquine, touted by President Donald Trump and his allies as a treatment and preventative for the pandemic disease Covid-19, does not keep people from getting sick. A large, randomized study, scheduled to appear today in The New England Journal of Medicine shows that the drug is no better than a placebo at preventing infection in people exposed to the virus under real-world conditions. This was a careful, well-planned trial—one of the most rigorous tests of hydroxychloroquine yet completed.
