India may be seeing a surge in daily COVID-19 infections but deaths and cases of severe illness are significantly lower compared to the second wave because of a high rate of vaccination, the government said on January 20.

Addressing a press conference, Indian Council of Medical Research director-general Dr Balram Bhargava said vaccines had proven beneficial.

"Deaths have considerably reduced due to vaccinations. In this third surge of COVID19, we are currently not witnessing severe illness and deaths due to high vaccination uptake,” he said. Health secretary Rajesh Bhushan were also present in the press conference.

As many as 94 percent of India's adults have been given the first dose, while 72 percent are fully vaccinated.

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.
