I've heard and seen success testimonies of its use for covidvirus treament. Dr. Vladimir Zelenko, for example. No one from whom the doctors treated with hydroxychloroquine have died, but recovered. My question is , why is the mainstream media peachy dark and silent about this good news? And perhaps, they should investigate intensively and thoroughly; and rate or disprove the scientists and doctors on the use of the therapeutic drug ZPac themselves.
