Trump – and some of his fans – may be taking hydroxychloroquine to try and ward off Covid-19.
But there's not much to indicate the drug actually stops you from getting Covid-19.
The drug, which is commonly used to treat Malaria and autoimmune diseases, has become somewhat of a right-wing talking point in the last week, particularly since Trump said at one of his daily press conferences that he was taking it as a prophylactic.
To be clear, there is little to no evidence to suggest that it can be used in this way, especially when self-administered.
