The participant was hospitalised with viral pneumonitis, a couple of days after being administered the vaccine. He was discharged after a week’s stay in the hospital.

According to Bharat Biotech, the adverse incident was probed thoroughly and it was found that the adverse event was not related to the vaccine.

‘All treatment costs for the subject was fully paid for by the sponsor, and the subject is safe,’ Bharat Biotech said.

As per the guidelines laid down by the Centre, all adverse events are to be reported to the site ethics committee, CDSCO-DCGI, data safety monitoring board and sponsors.

Bharat Biotech is conducting three-stage clinical trials of Covaxin, a wholly-inactivated novel coronavirus vaccine, in collaboration with apex bio-research agency, the Indian Council of Medical Research.

Bharat Biotech is one of the few companies to conduct human challenge studies at Oxford University, United Kingdom while it’s is also conducting other clinical trials in the US and UK.
