PM Modi says 100-crore-vaccine achievement answers doubts about India's capabilities

"Questions were raised whether India will be effectively able to combat the pandemic. Whether we will be able to procure the vaccines and innoculate our population. This achievement has answered all those questions once and for all," the Prime Minister said.

A day after India reached a landmark of 100 crore COVID-19 vaccination jabs, Prime Minister Narendra Modi said that the achievement was because of the efforts of each and every citizen.

"Many are comparing the vaccination programme to that of other countries. There has been a lot of praise. However, it is forgotten how we started," Modi said in an address to the nation on the morning of October 22.

"Questions were raised whether India will be effectively able to combat the pandemic. Whether we will be able to procure the vaccines and innoculate our population. This achievement has answered all those questions once and for all," the prime minister said.

No country other than China has achieved this landmark. What makes it even more remarkable is the slow, rather fraught, start that India’s vaccination programme made after its start on January 16.

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.
