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.

Addressing the daily press conference, Union Health Secretary Rajesh Bhushan confirmed that India was considering a tie-up with Pfizer.

How many doses of the vaccine will be made available? 

The firm said it was aiming to produce up to 50 million vaccine doses in 2020 and 1.3 billion in 2021.

What are some of the challenges? 

While the UK has ordered enough Pfizer vaccine for 20 million people, it’s not clear how many will arrive by year’s end. Adding to the distribution challenges that primarily involve storage, where Pfizer's vaccine needs to be stored at ultra-cold temperatures.

As for providing a vaccine to India, Adar Poonawalla, CEO of Serum Institute of India (SII), had estimated a need for close to 15 billion doses of the COVID-19 vaccine if a two-dose programme – similar to the measles vaccinations drive –  is initiated.

When will the vaccine be ready for use? 

According to what the firms have revealed today, it should start arriving in the UK within days and could be used on British citizens from next week.

What are some of the other options currently being considered in India? 

COVISHIELD, currently being developed by the SII is in the process of applying for emergency use license for its COVID-19 vaccine. It is manufacturing 50-60 million doses per month, and from January, it would increase the production to 100 million doses per month.

Bharat Biotech and ICMR have already started the phase 3 trial of the indigenously developed COVAXIN jab.

Zydus Cadila will apply for Phase 3 clinical trials of its experimental COVID-19 vaccine in December and expects to launch it by March 2021.

Infact, Russia's Sputnik-V COVID-19 vaccine might become available for supply as early as next month. According to Kirill Dmitriev, Chief Operating Officer of RDIF, they are hoping for approval in January 2021, and are "ready to supply the vaccine to a wider population within the same timeframe".
How much will it cost? 


While it is not yet known how much the vaccine will cost, existing health insurance policies are unlikely to cover the cost of vaccination and adverse reactions, if any.

Insurance sources told Moneycontrol that only policies designed purely for the COVID-19 vaccination process would help bear the costs.
