Vaccinated but stuck: Indians await WHO nod for homegrown shot to travel abroad

Like Sugathan, millions of Indians have taken Covaxin and many have complained of travel struggles as the vaccine has not been recognised for international travel by several countries.

India Stuck in a village in southern India for nine months and unable to return to his job in Saudi Arabia, Sugathan P.R. is hoping the World Health Organization will approve the Indian COVID-19 shot Covaxin, paving the way for his trip back.

Like Sugathan, millions of Indians have taken Covaxin and many have complained of travel struggles as the vaccine has not been recognised for international travel by several countries.

"I cannot continue to remain idle here any further," said 57-year-old Sugathan, who returned to Pandalam village in Kerala in January to be with his family after missing his father’s funeral last year when the pandemic disrupted flights.

"I had the option of going to Saudi and taking (additional doses of) Covishield after a four-day institutional quarantine, but I was not sure of its implications on my health," said Sugathan, referring to AstraZeneca’s vaccine.

"If the Covaxin approval does not come, I will take the risk of going and taking a Saudi-approved vaccine," he added, sitting in his spacious two-storey house fronted by paddy fields.

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.
