Lancet retracts major Covid-19 paper that raised safety concerns about malaria drugs
The Lancet, one of the world’s top medical journals, on Thursday retracted an influential study that raised alarms about the safety of the experimental Covid-19 treatments chloroquine and hydroxychloroquine amid scrutiny of the data underlying the paper.
The retraction came at the request of the authors of the study, published last month, who were not directly involved with the data collection and sources, the journal said.
