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.

Though the firm stopped production of Covishield in December 2021, it could restart production, Poonawalla was quoted as saying in the report.

"We are on 'standby' to restart Covishield production if orders come in. We have an inventory of 200 million Covishield doses currently," Poonawalla stated.

Earlier on March 9, India’s drug regulator granted restricted emergency use authorisation to SII’s COVID-19 vaccine Covovax for the 12-17 years age group, subject to certain conditions.

Confirming the DCGI approval, Poonawalla tweeted: "@SerumInstIndia’s brand Covovax has completed bridging studies in India and has been granted Emergency Use Authorisation by DCGI for adults and for children above the age of 12. Younger age groups will follow shortly.”

It is the fourth vaccine to receive the regulator’s nod for use among those below 18 years.

However, only one vaccine –Bharat Biotech’s Covaxin– is used for the 15-18 years age group in the vaccination drive in the country after the government approval.
