India is likely to approve Oxford/AstraZeneca’s coronavirus vaccine for emergency use by next week after its local manufacturer submitted additional data sought by authorities, two sources with knowledge of the matter told Reuters.

India, the world’s biggest vaccine-making country, wants to start inoculating its citizens next month and is also considering emergency use authorisation applications for vaccines made by Pfizer Inc and local company Bharat Biotech.

Getting vaccines to the world’s second-most populous country with one of the highest infection rates will also be a big step in the battle against the pandemic.

The AstraZeneca-Oxford shot is considered vital for lower-income countries and those in hot climates because it is cheaper, easier to transport and can be stored for long periods at normal fridge temperatures.

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.
