The Indian Council of Medical Research (ICMR) is planning to study whether the novel coronavirus strain in India has undergone mutation while spreading within the country over the last two months.

According to a senior scientist of the country's apex health research body, determining whether or not the SARS-CoV2 strain has changed form will help in ensuring the effectiveness of a potential vaccine.

"The study will also indicate whether it has become more virulent and increased transmission capability."

Samples will be collected from COVID-19 patients to study whether the novel coronavirus strain has mutated or not, he said.

However, the study can begin once the lockdown is lifted since currently there are difficulties involved in transportation of samples from different states and Union Territories, scientists 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.

Coronavirus India LIVE Updates

As per Global Initiative on Sharing All Influenza Data (GISAID), so far the maximum difference in the novel coronavirus strain in India has been found to be between 0.2 to 0.9 per cent as compared to the strains in other countries, another scientist said.

GISAID, which promotes international sharing of all influenza virus sequences and related clinical and epidemiological data, has over 7,000 complete genome sequences of SARS-CoV2 deposited by various laboratories across the world where they have classified the virus based on their mutations.

There are chances that people arriving in India from different countries are bringing various strains of the virus.

Three strains of the virus have been traced in India so far. One was from Wuhan, and the other two from Italy and Iran. The sequence of the coronavirus strain from Iran was similar to that of China.

"It will take some time for us to know the predominant quasi-species of the novel coronavirus in the country. But mutations are not likely to make potential vaccines ineffective, as all sub-types of the virus have the same enzymes. Also, it has been in India for three months and it does not mutate very fast," Head of Epidemiology and Communicable Diseases at ICMR Dr Raman R Gangakhedkar had said earlier.

Six Indian companies are working on a vaccine for COVID-19, joining the global race to find a preventive for the deadly infection spreading rapidly across the world.

Nearly 70 'vaccine candidates' are being tested and at least three have moved to the human clinical trial stage, but a vaccine for the novel coronavirus is unlikely to be ready for mass use before 2021.

India has also collaborated with WHO's multi-country "solidarity trial" for developing potential treatments and drugs for COVID-19.

The death toll due to COVID-19 rose to 1,218 and the number of cases climbed to 37,336 in the country on Saturday, according to the Union Health Ministry The number of active COVID-19 cases stood at 26,167, while 9,950 people have recovered and one patient has migrated.
