Coronavirus vaccine | Centre looking at priority group of 300 million, not entire population for COVID-19 vaccination: Dr VK Paul

Dr VK Paul said that the government's main goal is to stall the spread to COVID-19 transmission and ensure the entire nation has herd immunity.

The head of the National COVID-19 Task Force, Dr Vinod K Paul on January 1 said that the Centre is currently looking at priority group of 300 million and not the entire population for vaccination against the disease.

The National COVID-19 Task Force chief made the comments while speaking to CNBC-TV18 even as the Subject Expert Committee (SEC) of the Central Drugs Standard Control Organisation (CDSCO) recommended emergency use authorisation (EUA) "with conditions" for Serum Institute of India's (SII) Covishield vaccine, sources said.

"India has decided that it will pitch for 300 million individuals," Dr Paul told the news channel in an exclusive interview, adding that the immediate phase will begin with nationwide vaccination of healthcare workers.

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.
