What ‘clinical trial mode’ label means

The ‘clinical trial mode’ label meant that the manufacturer of Covaxin, Bharat Biotech had to seek informed consent before administering its vaccine to those eligible for the government’s ongoing vaccination drive.

It also meant the company had to submit updates on the safety, immunogenicity, and efficacy of the vaccine from its phase 1, 2, and 3 clinical trials more regularly than SII, which has had to submit such data every 15 days so far.
