Bharat Biotech has recruited 23,000 volunteers and continued to progress towards achieving the goal of 26,000 participants for Phase-3 clinical trial of its COVID-19 vaccine Covaxin across multiple sites in India, the company said.
Covaxin is being developed by Bharat Biotech jointly with the Indian Council of Medical Research (ICMR)- National Institute of Virology (NIV).
The Phase III human clinical trials of Covaxin began mid-November, targeted to be done in 26,000 volunteers and it is the country's first and only Phase III efficacy study for a COVID-19 vaccine, a press release from the vaccine maker said on Saturday night.
