President Trump’s taking hydroxychloroquine, but what about the rest of us?

Hydroxychloroquine has been used for decades to treat malaria, lupus, and other conditions and no-one’s batted an eye-lid… until now. Last week President Trump suddenly announced he was taking it to prevent getting Covid-19. He’s actually been touting its benefits for months. A number of political opponents, medical professionals and journalists immediately railed against the President’s advice but scientists around the world are currently trialling the drug as a preventative medication… Is it useful or not?
