The federal government aimed to vaccinate about 300 million folks by August. As of Wednesday, it had inoculated about 16 million. At that charge, masking the inhabitants might take years. The authorities have expanded eligibility from important staff to incorporate folks over 60 and people above 45 with vital well being dangers.

Final week, an advisory board for Central Medicine Commonplace Management Group, India’s pharmaceutical regulator, rejected Bharat Biotech’s request for a Covaxin trial on kids between the ages of 5 and 18, saying the corporate ought to first submit a report on the efficacy of its vaccine.

The uncertainty might hinder Bharat Biotech’s ambitions to promote Covaxin to international locations like Brazil. Final week, prosecutors there sought the speedy suspension of Covaxin purchases after the federal government signed a contract to purchase 20 million doses.

The corporate has been undaunted. Bharat Biotech, which developed Covaxin with the Nationwide Institute of Virology and the Indian Council of Medical Analysis, has already equipped 5.5 million pictures of its vaccine for the Indian authorities’s vaccination marketing campaign.

On Wednesday, the corporate mentioned the ultimate stage of the Covaxin trial had concerned 25,800 volunteers throughout the nation.
