As India completes one month of COVID-19 vaccination, here is all one needs to know

India had launched its COVID-19 vaccination drive on January 16. In the initial phase, three crore healthcare and frontline workers across the country are being inoculated.

India deployed two COVID-19 vaccines for the rollout; one is Serum Institute of India’s (SII) Covishield and the other is Bharat Biotech's, Covaxin. While Covishield was given restricted emergency use approval (EUA) by the government, Covaxin was allowed EUA on clinical trial mode, as the vaccine hasn't yet submitted the Phase-3 efficacy data. Both the vaccines have to be given in two doses.

India reported 10.8 million Covid-19 cases, with a recovery rate of around 97 percent, which is one of the highest in the world.

Here is an explainer on where India stands in terms of vaccination numbers; details about the second dose; has India overcome vaccine hesitancy and what are the challenges in the way of increasing vaccination speed?

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.
