Dr. Anthony Fauci has again stressed the determinations by health officials that hydroxychloroquine is ineffective in combatting the coronavirus after President Donald Trump continued to baselessly endorse its use this week.

Hydroxychloroquine is not effective in the treatment of coronavirus disease or COVID-19, Fauci, the director of the National Institute of Allergy and Infectious Diseases, said on MSNBC on Wednesday. He cited the results of numerous clinical trials that he said have consistently shown this.

If a study thats a good study comes out and shows efficacy and safety for hydroxychloroquine or any other drug that we do, if you do it in the right way, you accept the scientific data, said Fauci, a key member of Trumps Coronavirus Task Force. But right now today, the cumulative scientific data that has been put together, and done over a number of different studies, has shown no efficacy.
