A woman tested positive for coronavirus at the Indore airport following which she was prevented from boarding the Air India’s Dubai-bound flight on December 29, an official said.

The 44-year-old Dubai resident has already taken four doses of two different vaccines against COVID-19, the official said.

“As per the standard practice, rapid RT-PCR tests are conducted during the weekly Indore-Dubai flight and as part of it, 89 passengers were tested today. A woman among them was found infected with the coronavirus,” Indore Health Department’s Medical Officer Dr. Priyanka Kourav told PTI.

The woman had arrived in Mhow town near Indore in Madhya Pradesh 12 days back to attend the marriage of a close relative, the official said.

She had taken two doses each of Sinopharm and Pfizer’s anti-COVID-19 vaccines between January and August, the official said.

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.

As of now, the woman is asymptomatic. But, she informed the airport’s health staff that she was suffering from cold and cough four days back, Dr. Kourav said.

The Health Department staff got her admitted to a government hospital in Indore, she added.

In the last few months, two women and a man were stopped from boarding the Indore-Dubai flight, being run every Wednesday, after they tested positive for the viral infection at the airport.
