Many physicians, doctors, scientists, including Trump’s own advisor, Dr. Anthony Fauci
, have emphasized that in order to know if a drug is going to work to treat and prevent COVID-19– and be safe — it is must to be studied in clinical trials. It might to do work, but it might not. It is possible that the use of the drug proved be safe, but it also could hurt patients.
Clinical trials are believed to be the gold standard in medicine. Boiled down to the essentials, clinical trials take a large group of people, give half of them the drug and half of them a placebo, and see how each group responds. If the majority of the clinical trials give positive results then we can use the specific drug to treat the virus but it is is too early to assume that the drug will work to prevent and cure the COVID-19.
