At least 100 people in Bhopal city who were in a trial of Covaxin, one of two Covid-19 shots approved in India, alleged that the hospital conducting the trial did not inform them that they were test subjects.
The allegation comes as India prepares to vaccinate 30 million front-line workers from Saturday.
"A van with loudspeakers came announcing a free corona vaccine. They did not tell us this is a trial,"
