Sao Paulo (CNN) Brazilian President Jair Bolsonaro has long been a champion of drugs chloroquine and hydroxychloroquine to cure Covid-19, despite multiple studies that show that they are not effective . After repeatedly promoting the potential for chloroquine and hydroxychloroquine to both prevent and mitigate the effects of Covid-19, Bolsonaro himself tested positive last July. The Army told CNN Brasil that between September 2020 and January 2021, 420,000 doses were distributed. CNN Brasil first reported on the existence of the letter last month. Brazil's Health Ministry responded to CNN Brasil saying the terms of the offer, which included an agreement not to hold Pfizer responsible for negative side effects, were "abusive."
