A passenger on board an Air India flight, which was bound to travel between Delhi and Ludhiana, tested positive for the novel coronavirus on May 26. Following this, all the passengers travelling along on the flight were put under state quarantine, news agency ANI has reported.
According to the report, the passenger - an employee in the security department of Alliance Air - was travelling on flight number AI9I837 on a paid ticket.
The infected person is a resident of Delhi and works as security staff with Air India, reported NDTV citing Deputy Commissioner Pradeep Agrawal, who added that the person had arrived on May 25 by a domestic flight at the Sahnewal Airport.
The COVID-19 patient was sent to a local isolation centre while others were sent on mandatory home quarantine, said the report.
Frequently Asked Questions
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.
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.
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.
