81% of 401 Punjab samples show UK variant, Amarinder Singh asks PM Modi to widen vaccine ambit

Expressing concern over the COVID-19 situation, the chief minister also appealed to people to get themselves vaccinated and stressed the need for the Central government to urgently open up vaccination for a larger section of the population.

Eighty-one per cent of the 401 samples sent by the government for genome sequencing have tested positive for the UK variant of COVID-19, Punjab Chief Minister Amarinder Singh said on Tuesday, and asked the Centre to widen the vaccination net to cover those younger than 60.

Expressing concern over the COVID-19 situation, the chief minister also appealed to people to get themselves vaccinated and stressed the need for the Central government to urgently open up vaccination for a larger section of the population.

He urged Prime Minister Narendra Modi to widen the vaccination ambit to cover those younger than 60 as the mutant has been found to be infecting young people more, an official statement quoting him said.

The process needs to be expedited," he said, pointing to the fact that experts had found the Covishield vaccine to be equally effective against the UK variant - B.1.1.7. It was essential to vaccinate more and more people to break the chain of transmission, he said.

The state government, which has already announced fresh restrictions, would be forced to impose more curbs if people don't follow Covid appropriate behaviour, Amarinder Singh warned.

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.

The appeal from the chief minister came after head of the state's Covid expert committee Dr K K Talwar apprised him of developments on the new variant in the state, which has been witnessing a surge in the number of cases in the last few weeks.

The chief minister had been informed by Talwar that though the UK variant B.1.1.7 is more infectious it is not more virulent.

The state health department had sent 478 COVID positive samples to NIB (National Institute of Biologicals), IGIB (Institute of Genomics and Integrative Biology, Delhi), and NCDC (National Centre for Disease Control) for genome sequencing, of which results of 90 samples were received and those showed only two samples for N440K (a coronavirus variant).

Subsequently, a team from the Ministry of Health & Family Welfare, Government of India, visited the state to review the increase in positivity, the statement said. The team was also informed about the pending results of genome sequencing, it added.

Thereafter, 401 more samples, collected between 1.1.2021 to 10.3.2021, were sent to NCDC for genome sequencing. The result of these samples was worrying as it showed presence of B.1.1.7 variant in 326 COVID samples, the statement said quoting Talwar.

On Monday, Punjab reported 2,319 fresh COVID-19 cases, taking the tally to 2,15,409, and 58 fatalities, pushing the death toll to 6,382.
