Many countries, including India, might have embarked on ambitious vaccination drives to curb coronavirus infections, but the airline industry is still waiting for global guidelines on overseas travel for individuals vaccinated against COVID.

An official of the International Air Transport Association (IATA) on Monday told PTI that regulations and restrictions to travel are determined by governments, but expressed hope that governments will consider relaxing travel restrictions for vaccinated persons.

A global airlines' grouping, IATA has nearly 290 members, including Air India, IndiGo, Vistara and SpiceJet.

While air traffic is picking up in different parts of the world, regulations on travel are decided by respective governments of countries and there are expectations that the World Health Organisation (WHO) might come out with global guidance that will help air travel of vaccinated passengers.

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.
