Amid fear of new COVID-19 strains, RT-PCR test is compulsory for passengers arriving from seven more countries, including South Africa, Bangladesh and China, the Centre said on Thursday.

In a letter to all states and Union territories (UTs), the government said considering reports of new mutations in SARS-CoV-2 and rising number of Variants of Concern (VOCs) and Variants of Interest (Vols) globally, seven countries have been added in the list of countries whose travellers will have to get another RT-PCR test done upon landing at Indian airports apart from the one they need to get before embarking on the flight.

These seven countries are South Africa, Bangladesh, Botswana, China, Mauritius, New Zealand and Zimbabwe.

In earlier guidelines issued in February, passengers from only the United Kingdom, Europe and the Middle East had to get the RT-PCR test done again upon landing at Indian airports.

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.
