India administered more than 30.9 lakh COVID-19 vaccine doses in the last 24 hours, taking the vaccination count beyond 107.7 crore, according to the Union Health Ministry update on November 5.

On the 293rd day of the nationwide vaccination drive, over 2.01 lakh people received their first shot and 3.63 lakh their second dose.

The vaccination drive accelerated over the last few weeks. It took the country 85 days to give the first 10 crore doses, the next 10 crore took 45 days and, in another 29 days, India touched the 30-crore mark.

By the following 24 days, the count reached 40 crore and crossed the 50-crore mark after 20 days on August 6. By September 13, 75 crore vaccine doses were given. The biggest jump, however, came on September 17, when more than 2.1 crore shots were given in one day.

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.
