A day after aviation regulator Directorate General of Civil Aviation warned airlines to ensure declaration by passengers or face action, it has emerged that an Air India flight from Milan to Delhi came without screening fliers for the coronavirus.

News agency ANI posted on Twitter that screening was done after the flight landed in Delhi. It should have done at Milan, itself.

COVID-19 Vaccine Frequently Asked Questions View more 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. View more Show

"Air India AI-138 from Milan to Delhi has been taken to isolation bay at Delhi Airport; currently, all passengers are going through screening at the airport," the post added.

On March 10, the DGCA issued a circular saying that some of the airlines had not ensured availability of self-declaration forms to passengers.

"This has been viewed very seriously by this office. All airlines operating on international sector, therefore, are again advised to ensure availability of self-declaration forms," the DGCA said.

The regulator added that all airlines should also ensure in-flight announcements regarding the same.

A government official confirmed that the Air India incident had prompted the circular. "The violation is serious enough to stop their operations," the official added.

There are more than 60 confirmed cases in India now.
