Covid-19: Mexico City gave ivermectin kits to people with covid in “unethical” experiment

The government of Mexico City handed out nearly 200 000 “ivermectin based kits” last year to people who had tested positive for covid-19, without telling them they were subjects in an experiment on the drug’s effectiveness. The results of that experiment were then written up by public officials in an article placed on popular US preprint server SocArXiv.1 It became one of site’s most viewed articles, claiming that ivermectin had reduced hospital admissions by 52-76%. But those officials have been under fire at home since SocArXiv withdrew the paper earlier this month, calling it “either very poor quality or else deliberately false and misleading.” Opposition deputies in Mexico City’s Congress demanded hearings and said they would bring legal action against the paper’s lead author, José Merino, head of the city’s Digital Agency for Public Innovation. Explaining the decision to withdraw the article—the first to be taken down by SocArXiv—the site’s steering committee wrote that it had responded “to a community groundswell beseeching us to act” in order “to prevent the paper from causing additional harm.”2
