COVID-19 vaccine update: Centre plans to vaccinate 20-25 crore Indians by July 2021

The doses are being procured by the government and will be enough to inoculate about 25 crore of India's 130 crore population. Priority will be given to frontline health-care workers, Health Minister Harsh Vardhan said.

The Centre expects to receive 40-50 crore doses of a vaccine for COVID-19 by July 2021, Health Minister Harsh Vardhan said on October 4. The doses should be enough to cover 20-25 crore people when delivered.

The procurement and equitable delivery of the vaccines, including those by Indian vaccine manufacturers, will be given "full government support", the Health Minister said during his weekly public interaction on 'Sunday Samvad' platform.

The doses are being procured by the government and will be enough to inoculate about 25 crore of India's 130 crore population. Vardhan said priority will be given to frontline health-care workers.

A high-level expert group is going into all aspects of vaccines and the health ministry is currently preparing a format in which states will submit lists of priority population groups to receive a vaccine, the Union minister said.

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.
