Genomics can help in a big way in healthcare, fight against COVID: Rajnath Singh

Defence Minister Rajnath Singh said that through COVID genome sequencing, the part of the genome which is not changing frequently can be identified and it will help in vaccine development.

Genomics would be a major area in the 21st century and help in a big way in healthcare, the fight against COVID-19, increasing productivity and contributing to fighting challenges like climate change, Defence Minister Rajnath Singh said on Thursday.

He said that through COVID genome sequencing, the part of the genome which is not changing frequently can be identified and it will help in vaccine development.

He noted that while Information Technology (IT) played an important role in the 1990s in strengthening the country's economy, genomics would be a major area in the 21st century and play a crucial role in the country's and societal development.

Observing that climate change is going to be a major problem in the future, he said genomics can contribute in fighting the challenges. "Along with health and treatment, it can also be used in increasing productivity," he said in a video message on the occasion of inauguration of NKC Centre for Genomics Research.

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.
