'India scripts history,' PM Modi says, as nation reaches 100-crore COVID jab milestone

India’s stupendous 1 billion dose feat comes on the back of a slow start due to huge supply bottlenecks, vaccine hesitancy in the initial period and a crippling second wave of the pandemic.

As India reached an extraordinary milestone of giving away 100 crore COVID-19 vaccine doses on October 21, Prime Minister Narendra Modi congratulated the nation and expressed gratitude to doctors, nurses, medical and frontline workers.

"India scripts history. We are witnessing the triumph of Indian science, enterprise and collective spirit of 130 crore Indians. Congrats India on crossing 100 crore vaccinations. Gratitude to our doctors, nurses and all those who worked to achieve this feat," the Prime Minister tweeted.

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 had made after its start on January 16, 2021.

The vaccination drive started with inoculating healthcare workers in the first phase followed by non-medical frontline personnel like police, paramilitary, armed forces, sanitation and municipal workers, senior citizens in the subsequent phases.

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.
