Few takers for COVID-19 vaccine booster doses but surge in cases may change that

With the Covid pandemic easing, most cases being mild, and the requirement of a nine-month gap from the second dose, most people have stayed away from vaccination centres

Daily COVID-19 case levels and positivity rates in some states may be showing signs of an uptick but the majority of Indians, it seems, is not interested in availing booster doses, which were opened for all adults beginning April 10.

Over a week after the government authorised private hospitals across India to offer precautionary doses of COVID vaccines to all those above 18 years, only 1.84 lakh doses had been administered to the 18-59-year age group till April 18.

A closer look at the data suggests that 1.42 lakh booster doses had been administered to the 45-59 age group in the first nine days. The figure was even more abysmal for the 18-44-year age group, at 41, 394.

Overall, just about 2.55 crore booster doses have been administered so far.

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.
