Chief Minister Arvind Kejriwal will discuss the existing COVID-19 situation with top officials at a high-level meeting on Tuesday during which a decision is also likely to be taken on implementing the Graded Response Action Plan in Delhi, officials sources said.

The chief minister will chair the meeting at 12 noon. It will discuss the rising number of COVID-19 cases and threat posed by its new variant Omicron. Besides, the meeting may decide on sounding the 'Yellow' alert and restrictions according to the GRAP, according to the sources.

The 'yellow' alert is sounded when Covid positivity rate stays over 0.5 per cent on two consecutive days. It involves restrictions like night curfew, closure of schools and colleges, alternate day opening of shops of non-essential items and halved seating capacity in Metro trains and public transport buses among others.

Delhi on Monday recorded 331 fresh COVID-19 cases, the highest single-day rise since June 9, and one death while the positivity rate mounted to 0.68 per cent, according to data shared by the city health department.

On Sunday, Delhi recorded 290 cases with a positivity rate of 0.55 per cent and one fatality, according to officials figures. In view of the rising number of COVID-19 cases, the Delhi Disaster Management Authority (DDMA) has already imposed night curfew that will remain in force in the city from 11 pm to 5 am, till further orders.

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.
