A decision on Bharat Biotech’s submission seeking emergency use listing (EUL) for its Covaxin COVID-19 vaccine will be made in October, the World Health Organisation has said.

The status of assessment for Covaxin is “ongoing”.

Bharat Biotech had submitted EOI (Expression of Interest) on April 19 for its vaccine.

The latest ‘Status of COVID-19 vaccines within WHO EUL/PQ evaluation process’ guidance document dated September 29 on the WHO website said that the decision date for Bharat Biotech’s Covaxin is “October 2021”.

The WHO said it began rolling data of the vaccine on July 6. Rolling data allows the WHO to start its review right away, as information continues to come in, to accelerate the overall review process.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

According to the WHO, submissions to WHO for prequalification or listing under the emergency use procedure are confidential.

If a product submitted for assessment is found to meet the criteria for listing, the WHO will publish the results widely.

Duration of the emergency use listing process depends on the quality of the data submitted by the vaccine manufacturer and on those data meeting WHO criteria, according to the agency.

Bharat Biotech's Covaxin and AstraZeneca and Oxford University's Covishield are the two widely used vaccines in India.

Bharat Biotech recently said it submitted all data pertaining to Covaxin to the WHO for EUL and is awaiting feedback from the global health watchdog.

"#COVAXIN clinical trial data was fully compiled & available in June 2021.

All Data submitted for Emergency Use Listing (EUL) Application to World Health Organization in early July. We have responded to any clarifications sought by #WHO and are awaiting further feedback," Bharat Biotech had tweeted earlier this month.

“We are diligently working with the WHO to obtain EUL at the earliest,” the company had said on Tuesday.
