We can only give COVID-19 vaccines to govt of India at the moment: Serum Institute CEO Adar Poonawalla

With rich nations reserving most COVID-19 vaccine doses made this year, Serum Institute is likely to make most of the inoculations for developing countries. However, the ban would mean that poorer nations will have to wait longer before receiving their first shots.

India will not allow the export of the Oxford University-AstraZeneca coronavirus vaccine for several months, the head of Serum Institute of India, which has been contracted to make 1 billion doses of the vaccine for developing nations, said Sunday.

With rich nations reserving most of the vaccines that will be made this year, Serum Institute — the world’s largest vaccine manufacturer — is likely to make most of the inoculations for developing countries. The ban on exports, however, means that poorer nations will probably have to wait a few months before receiving their first shots.

The vaccine was granted emergency authorization by the Indian regulator on Sunday, but on the condition that Serum Institute doesn't export the shots to ensure that vulnerable populations in India are protected, Adar Poonawalla, the company's CEO, said in a phone interview with The Associated Press.

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.
