Amid spike in COVID-19 cases in several countries, the Union Health Ministry on December 22 asked the Civil Aviation Ministry to ensure that samples of 2 percent of international passengers in every flight is tested for coronavirus.

Additionally, the Centre also stated that if found positive, these samples will be subjected to genomic sequencing. The passengers, from whom random samples would be collected, however can leave airports after submitting samples, it added.

Meanwhile, earlier today, Union Health Minister Mansukh Mandaviya said that random sampling of travellers arriving at international airports has begun.

"We have also started the random RT-PCR sampling among passengers arriving at International airports in the country. We are committed to tackling the pandemic and are taking appropriate steps," Mandaviya said in his statement in the Lok Sabha while advising the states to make sure that people wear masks, use sanitisers and maintain social distancing even during the festive and the New Year season.

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.
