Union Health Minister Mansukh Mandaviya, on December 21, directed officials to isolate the current SARS-CoV-2 virus in circulation in the country and check if the existing vaccines are effective against it.

The minister also directed officials and experts to stay alert and step up surveillance in the wake of rising coronavirus cases in some countries, especially China, in a high-level meeting to review COVID-19 status and preparedness in the country.

“COVID-19 is not over yet,” Mandaviya tweeted after the meeting. “I have directed all concerned to be alert and strengthen surveillance. We are prepared to manage any situation”.

This comes a day after Union Health Secretary Rajesh Bhushan wrote to all states saying that in view of the sudden spurt of cases being witnessed in Japan, United States, South Korea, Brazil and China, it is essential to gear up the whole genome sequencing of positive case samples to track the variants through Indian SARS-CoV-2 Genomics Consortium (INSACOG) network.

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.
