DDMA nod for colour-coded action plan to deal with possible 3rd Covid wave

The colour codes based on positivity rate (on two consecutive days), cumulative number of new cases (over a week) and average oxygenated-bed occupancy (for a week) will designate four levels of alerts, officials said.

To deal with a possible third wave of coronavirus, the Delhi Disaster Management Authority (DDMA) passed a colour-coded response action plan on Friday under which curbs will be implemented in accordance to the severity of the COVID-19 situation.

At a DDMA meeting chaired by Lieutenant Governor Anil Baijal, experts stressed on having 12,000 ICU beds, sufficient oxygen, drugs and ambulances to deal with another surge in cases in the city.

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.
