Bharat Biotech announced the commencement of phase-3 trials of Covaxin. There will be around 20000 volunteers who will participate during the third trial. But, one of the conditions is that the minimum age of volunteers should be 18 years. Even those who had been tested positive are also not eligible to participate in this.
