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.

In Karnataka, one person has been discharged, while the other is reported to be stable, but under observation at the District Hospital in Chitradurga.

Rajasthan reported a case of suspected anaphylaxis, but the vaccine beneficiary is fine now and has been kept under observation at the District Hospital in Bangar.
The Health Ministry has said "0.18 percent adverse events happened following immunization and 0.002 percent of people were hospitalized following immunisation. These are fairly low and the lowest so far in the world in the first three days".

The government, on January 16, launched the COVID-19 vaccine drive. Oxford-AstraZeneca’s COVID-19 vaccine Covishield, which is being manufactured by Serum Institute of India, and Bharat Biotech's Covaxin are being administered to the beneficiaries.

In the initial phase, the country will inoculate about one crore healthcare workers. This will be followed by two crore front-line workers, police, armed forces, municipal workers, revenue staff and others. In the third phase, 27 crore people above 50 years of age and those with co-morbidities like diabetes, hypertension, and organ transplant patients will get the vaccine.
