Pfizer India has become the first pharmaceutical firm to seek from the Drugs Controller General of India (DCGI) an emergency use authorisation for its COVID-19 vaccine in the country, after its parent company secured such clearance in the UK and Bahrain.

The firm, in its application submitted to the drug regulator, has sought permission to import the vaccine for sale and distribution in the country, besides waiver of clinical trials on Indian population in accordance with the special provisions under the New Drugs and Clinical Trials Rules, 2019, official sources said.

"Pfizer India has submitted an application on December 4 to the DCGI seeking emergency use authorization (EUA) for its COVID-19 vaccine in India. The firm has submitted the EUA application in Form CT-18 for grant of permission to import and market Pfizer-BioNTech's COVID-19 mRNA vaccine BNT162b2 in the country," the source said, citing the application.

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.
