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.

With this, the largest vaccination campaign in the history of the US has started, according to The Associated Press.

The development comes days after the US Food and Drug Administration (USFDA) on December 11 approved the Pfizer-BioNTech COVID-19 vaccine for emergency use.

That was the first COVID-19 vaccine candidate granted emergency use authorisation (EUA) in the Unites States, the country most affected by the pandemic.

The US has so far recorded nearly 16 million (1.6 crore) cases of the novel coronavirus and nearly 300,000 (3 lakh) deaths.

In a video statement released on Twitter, Trump had earlier said the US will start administering the Pfizer-BioNTech COVID-19 vaccine "in less than 24 hours" and will be "free for all Americans".

"Through our partnership with FedEx and UPS, we have already begun shipping the vaccine to every state and zip code in the country," he said, adding that governors would decide who would receive the shots first in their states.

US pharmaceutical giant Pfizer developed the vaccine against COVID-19 along with German company BioNTech. The mRNA vaccine candidate, administered in two doses, has been found to be 95 percent effective in preventing the disease.

"The FDA's authorization for emergency use of the first COVID-19 vaccine is a significant milestone in battling this devastating pandemic that has affected so many families in the United States and around the world," FDA Commissioner Stephen M Hahn said in a statement on December 11.

Residents in the United Kingdom (UK) have already begun receiving doses of the Pfizer-BioNTech on December 8, after the jab received emergency use authorisation in the country. Canada, Mexico, Saudi Arabia and Bahrain have also approved the vaccine candidate for emergency use.
