During my first tour in Afghanistan, all military personnel had to take chloroquine daily for the prevention of malaria. Nobody in my unit suffered any ill-effects from taking it. Somebody most likely in the medical or pharmaceutical profession had to have suggested this drug to Trump as a preventive for COVID-19. I doubt seriously Trump came up with this on his own.
A couple of hundred thousand troops taking this drug with no reports of deaths or serious illnesses reported, should have been an indicator that taking it did not result in serious illnesses and death as the MSM was making out after Trump's suggestion. I'm glad this BS study has been debunked, but unfortunately it will not be reported by the MSM.
