As travel begins to rebound, are employees of Indian airlines vaccinated?

The risk of infection spreading on airplanes is lower if Covid-19 protocols, including vaccination, are adhered to. Researchers say the danger of transmission is highest during meal services as well as boarding and departure procedures

In August, United Airlines became the first American carrier that required all its domestic employees to be fully vaccinated against COVID-19. United was so insistent on the vaccination drive that it moved to lay off employees who refused to get jabs. It has also since tried to use it as a competitive advantage.

What about India?

In the early days of the pandemic, before flights were halted and vaccines had been developed, airline pilots and crew were exposed to the virus as they continued to fly. Even after scheduled international flights were halted by India, Air India, IndiGo, SpiceJet, Vistara and Go First continued to operate international flights under the Vande Bharat scheme.

Over the course of the pandemic, some airline staff have paid a heavy price for not being vaccinated. In June this year, well after vaccines had become available, agencies reported that 17 pilots from private carriers and Air India had succumbed to Covid-19 in the previous month.

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.
