A number of different massive trials of hydroxychloroquine have been stopped or haven’t proven the drug to be efficient.

“No shock,” mentioned Dr. David R. Boulware, an infectious illness specialist on the College of Minnesota, who’s learning hydroxychloroquine as a preventive and an early therapy towards the coronavirus. He mentioned the proof is more and more clear that the drug doesn’t work in hospitalized sufferers. “Whether or not there’s any profit for pre-exposure prophylaxis or early therapy is as but unknown, however the function of hydroxychloroquine — if any — seems more and more uncertain.”
