You mean the same FDA who attempted to imprison Dr. Stanislaw Burzynski for finding an effective treatment for cancer? The same agency that wants to shut down adult stem cell research? That same agency who arrested a man who sold a mineral supplement (sodium chlorite) that purifies water and has been used in places like Africa by the Red Cross to prevent Malaria? Of course the FDA has approved chloroquine when its been in use since 1934 and used by all US military branches since World War II to the present for a protocol in preventing parasitic infections before going to tropical countries plagued with malaria.  It is even on the World Health Organization's List of Essential Medicines, the medicines needed in a health system that are considered to be the safest and most effective. So, what's the problem? There's no profit for Big Pharma! This is why the FDA is dragging their feet. They want a vaccine that they can get a compulsory mandate while making huge profits.
