Trials of a coronavirus vaccine have run into fresh controversy in Madhya Pradesh's Bhopal where some allege they received shots without informed consent. NDTV has spoken to over a dozen people who claim they were misled into taking part in trials held by a local private hospital, the People's College of Medical Sciences. They say they were not informed about the trial or the risks, but told only that the injection would prevent Covid. They also claim they were not given copies of the consent form, mandatory for such trials.
