Healthcare workers who take six or more doses of hydroxychloroquine (HCQ) enjoy “high” protection against the coronavirus infection, India’s health research agency claimed in a study published on Sunday that also underscores the need for other safety precautions. The study, published in the Indian Journal of Medical Research, declares no conflict of interest. But many researchers had cited evidence against hydroxychloroquine from other countries and questioned the absence of any published study from the ICMR. The researchers examined hydroxychloroquine intake retrospectively in a sample of 378 healthcare workers among 1,073 who had developed Covid-19 over the past two months, and 373 control healthcare workers who were not infected. But healthcare workers who took six or more doses were better protected than the others.
