India has put fliers from China, Japan, South Korea, Hong Kong and Thailand on its watch list. Air Suvidha form filling to declare current health status will be made compulsory for international passengers arriving from these countries as per the Centre's protocol.

The steps come amid a series of high-level meetings following a spike in cases seen in other parts of the world, although experts and officials have reportedly said India has little to worry because of its high baseline immunity.

India has ruled out any flights restrictions for now. “There are no direct flights from China to India and we are taking all possible precautions that we have learnt in the past two years to manage the spread of infection in the country. We are already randomly testing 2 percent samples for Covid from international passengers on arrival, and if required, in the future, we can increase it further and can also make it mandatory for all arriving passengers to get tested,” health minister Mansukh Mandaviya said in Rajya Sabha.

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.
