Explainer: Why India is relaxing export restrictions on COVID-19 vaccines

For one, India has to keep its commitment under a global initiative called COVAX. The other reason, as an expert says, is that if India doesn't ease export restrictions, it will benefit China, which is making deeper inroads into low and middle-income countries with vaccine diplomacy.

The government spent Rs 9,229.31 crore between March and July to procure 124 crore doses from three manufacturers.

Health and Family Welfare Minister Mansukh Mandaviya, on September 20, announced that the government would allow the export of COVID-19 vaccines in the fourth quarter of this year, and fulfil its COVAX commitment.

COVAX, or COVID-19 Vaccines Global Access, is a global initiative for the equitable distribution of jabs to people in low-and middle-income countries.

Easing supply situation

The supply situation of COVID-19 vaccines has eased considerably from a huge demand-supply mismatch in Q1FY22. The minister said more than 30 crore doses would be produced in October and more than 100 crores by December-end.

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.
