COVID-19 Vaccine

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.

Despite the fall in daily cases in the last several days, Chief Minister Arvind Kejriwal has cautioned that the chance of the third wave of the COVID-19 infections was quite real and asserted that his government was preparing on a "war-footing" to combat it.

Earlier today, the Delhi Disaster Management Authority (DDMA) issued an order to prohibit all celebrations of this year's Kanwar Yatra. This decision comes after both the state governments of Uttar Pradesh and Uttarakhand cancelled the Yatra.

Last week as well, DDMA passed a colour-coded response action plan under which curbs will be implemented in accordance with the severity of the COVID-19 situation to deal with a possible third wave of the pandemic. CM Kejriwal had also inaugurated a genome-sequencing laboratory at the ILBS hospital and said these labs will detect the lethality of the coronavirus variants and help the government prepare accordingly.

A total of 76,421 tests, including 52,490 RT-PCR and 23,931 rapid antigen tests, were conducted on July 16, according to the health bulletin on July 17.

In view of the improving COVID-19 situation, the Delhi government had announced the reopening of restaurants with 50% capacity and one weekly market per municipal zone from June 14. With a close gathering of shoppers in markets and restaurants resuming business amid phased unlock in the national capital, doctors have cautioned that Delhi could face a "worse than second wave situation" of COVID-19 if people do not adhere to safety norms or lower their guards.
