It was supposed to be a trip that would provide Ramesh Warrier* a welcome break from his worries. He had a lot to worry about. A loan of over Rs 3 crore that he was struggling to repay, and a  business that was just not taking off.

It was in February that Warrier had accompanied his mother to the US to visit his sister who was soon going to be a mother. No, he didn't have enough money to pay for the trip, it was his sister's gift.

But now he wished he hadn't gone to the US. Warrier and his mother are now stuck, at least till June, as flights to India have been suspended because of the lockdown.

And even beyond that it is still not clear if the government will allow flights to resume. Air India, the only Indian carrier to operate flights from the US, is accepting bookings only from June 1.

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.
