Chloroquine maybe the cure for Coronavirus we have all been waiting for so why are there calls for us to wait for "Clinical Trials?" This combination of drugs have been used to treat Malaria for sometime. It has already been Clinically tested and approve for use on Malaria. It's like taking aspirin for a headache then asking for clinical trials before using it to treat a knee pain. Why would you need to do that? The Body would not know why you are taking it.
