The cumulative COVID-19 vaccine doses administered in the country has crossed 81.73 crore with over 94 lakh doses being given on Monday so far, according to data on the CoWIN portal.

The daily vaccination tally is expected to increase with the compilation of the final reports for the day by late night.

Out of 81,73,95,763 doses administered so far, 64.8 percent eligible population received the first dose of COVID-19 vaccination and 22.2 percent received the second dose.

India on Friday administered a record number of over 2.50 crore COVID-19 vaccine doses on the occasion of Prime Minister Narendra Modi's 71st birthday.

The daily COVID-19 vaccination in the country was over 1 crore on September 6, August 31 and August 27.

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.
