Two passengers who travelled on SpiceJet flights from Ahmedabad to Delhi (SG-8194) and Delhi to Guwahati (SG-8152) have tested positive for COVID-19.

Tests were conducted at Guwahati after landing and the passengers were quarantined, according to a SpiceJet spokesperson. The reports came in on May 27, following which the operating crew has been quarantined while the passengers on the same flights are being notified by the airline in coordination with government agencies.

"The operating crew has been quarantined and SpiceJet is coordinating with government agencies in notifying other passengers who had travelled with them. SpiceJet has been strictly adhering to all SoPs and social distancing norms laid down by the government," the spokesperson said.

On May 25, domestic flight operations resumed after remaining suspended for over two months in light of the coronavirus -induced lockdown.

Passengers of other domestic flights have also been tested positive for the novel coronavirus. A passenger onboard a Chennai-Coimbatore IndiGo flight and another one headed from Delhi to Ludhiana on an Air India flight, both of whom undertook travel on May 25, tested positive for COVID-19.

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.
