How Serum Institute became the Jio of coronavirus vaccine deals

AstraZeneca is the latest deal that Pune-based Serum Institute has stitched together. How did the 50-year-old vaccine maker become the face of the Indian fight against COVID-19?

On June 4, British drugmaker AstraZeneca said it has partnered with Serum Institute of India to supply 1 billion doses of University of Oxford's potential novel coronavirus, or COVID-19, vaccine to low-and-middle-income countries (LMICs). Serum will provide 400 million doses before the end of 2020 as part of the arrangement.

The significance of the partnership is that if all goes according to plan, millions of Indians will get their hands on COVID-19 vaccine shots produced by Serum well before the end of 2020.

Partner of choice The AstraZeneca partnership is the latest in a series of arrangements that Serum, a 50-year-old privately-held company, has inked in recent months as the coronavirus pandemic spread across continents. Besides securing a licence to mass produce the University of Oxford vaccine, Serum has built an alliance with US biotech firm Codagenix. The latter will develop a live-attenuated vaccine (a weakened virus that doesn't cause disease but triggers immune response) to fight COVID-19, and Serum will invest in clinical trials, manufacturing and distribution.

Serum has also tied up with Austrian biotech company Themis Bioscience for another COVID-19 vaccine candidate that uses measles virus as a vector to inject an antigen or protein of SARS-CoV-2.

That’s not all. Serum also entered into a deal with Novavax. The Indian company sold its Czech Republic-based Praha Vaccines for roughly $167 million to Novavax, an American vaccine developer, which will produce a COVID-19 vaccine candidate in that facility. Serum and Novavax have partnered for a malaria vaccine and though it is still not clear whether Serum will extend the partnership to a COVID-19 vaccine, the possibility can't be ruled out.

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.
