Delhi Chief Minister Arvind Kejriwal took the second dose of COVID vaccine on Thursday and urged all eligible people to get themselves inoculated.
The chief minister, who has a history of diabetes, was administered the first dose of the vaccine at the LNJP Hospital here on March 4.
"I took my second dose of vaccine today. I urge everyone, whoever is eligible, to get vaccinated," Kejriwal said in a tweet after getting vaccinated.
The registration process for the vaccination of people in the 18-44 age group under the third phase of the inoculation drive has begun in the national capital. The Delhi government recently gave its approval for the purchase of 1.34 crore COVID vaccine doses.
Kejriwal is scheduled to chair a meeting later this evening on the third phase of the vaccination drive that is slated to roll out from May 1. Health Minister Satyendar Jain and senior officers will attend the meeting, officials said.
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.
