Serum Institute of India, the world’s largest vaccine maker by volume, is currently focused on catering to domestic demand for COVID-19 vaccines even as government officials hinted at a possible easing of export restrictions.

Serum Institute may start sending vaccines to other countries and COVAX, possibly by the end of the year, depending on the overall domestic supply situation, company executives said on condition of anonymity.

“Until July end, the supply situation is expected to remain tight, but beyond that things would ease,” another person said. Serum Institute is waiting for the green signal from the government, the person added.

The Centre had received flak for exporting vaccines earlier this year and putting its own population at risk. However, with vaccine supplies improving and the second wave receding, top government officials have indicated that restrictions on exports could be relaxed.

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.
