COVID-19 shots administered in India about to overtake count in all of Europe, North America

This is a remarkable feat, considering that all the vaccine doses administered in the country are made locally

Just shy of a landmark 200 crore COVID-19 vaccine doses, the shots administered in India against coronavirus are now about to surpass the total doses given in all of Europe and North America combined.

According to Our World in Data, India has now administered 1.95 billion shots against COVID-19 while this number is 1.29 billion in the case of Europe, 592.27 million in the case of the United States and 85.91 million in case of Canada.

This feat, interestingly, has been achieved despite the fact that the government’s push for booster doses for a large chunk of the population is yet to pick up the momentum.

The CoWIN dashboard, maintained by the Union government shows that as on June 20, 5.30 pm 1,96,17,60,546 vaccine doses against COVID-19 have been administered in India. Of these, 1,57, 07, 56, 208 doses are that of Covishield, followed by 32, 85, 70, 413 doses of Covaxin.

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.
