Bharat Biotech’s Covaxin shows 77.8% efficacy in Phase III trials

New Delhi, June 22

An expert panel of the country's central drugs authority has reviewed and accepted the phase-3 trial data of Bharat Biotech's Covid-19 vaccine Covaxin, sources said on Tuesday.

According to the data submitted by the Hyderabad-based firm, the indigenously developed vaccine has shown 77.8 per cent efficacy in the trial conducted on 25,800 subjects, they said.

The firm had submitted the results of its phase-3 trial efficacy data of Covaxin to the Drugs Controller General of India (DCGI) over the weekend, they added.

The Covid-19 Subject Expert Committee (SEC) of the Central Drugs Standard Control Organisation (CDSCO) on Tuesday reviewed the data and accepted it. Their recommendations have been sent to the DCGI now, a source said. 

Bharat Biotech is also expected to attend a "pre-submission" meeting on July 23 with the World Health Organisation (WHO), which will take the vaccine-maker closer to a WHO Emergency Use Listing (EUL).

Though the meeting will not be a detailed review on the product, the vaccine-maker will have an opportunity to submit a summary on the overall quality of the jab, according to the WHO.

The information was provided on the WHO website in the Status of Covid-19 Vaccines within WHO EUL-PQ evaluation process document.

Covaxin is one of the three vaccines approved by the DGCI for emergency use and is being deployed in India's Covid-19 vaccination programme. — PTI
