All the 112 people, housed at an ITBP quarantine facility after being evacuated from Wuhan in China, have tested negative for coronavirus after their first samples were taken, an official said on February 29.
"The samples of all the 112 people were sent to the AIIMS and the reports are negative. The quarantine period will continue for about a fortnight," a spokesperson for the border guarding force said.
Seventy-six Indians and 36 foreigners were taken to the Indo-Tibetan Border Police (ITBP) force quarantine centre in the Chhawla area of the national capital on February 27 after they were flown in from Wuhan city on an IAF transport plane.
The group of foreign nationals comprise 23 from Bangladesh, six from China, two each from Myanmar and Maldives, and one each from Madagascar, South Africa and the USA.
"The second samples of the inmates will be taken on the fourteenth day of the quarantine period and all those whose results are negative will be released from the ITBP centre," the spokesperson added.
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.
Earlier, India had similarly evacuated around 650 Indians from Wuhan on board two Air India flights who were kept at the same ITBP facility and one prepared by the Army in Manesar near here.
All these people were later found negative for the virus and they were allowed to go home after over a fortnight of quarantine.A team of doctors, paramedics and others will be present at the quarantine facility round-the-clock and the inmates will be provided facilities like food, bed and indoor entertainment to spend time, the spokesperson said.
