Hydroxychloroquine ineffective at preventing COVID-19 – Trial

The medicine has been touted by US President Donald Trump, who has said he used it as a prophylaxis against the novel coronavirus.
But an experiment involving 821 people across the United States and Canada showed it did not work significantly better than a placebo for this purpose.
