Serum stops making COVID-19 vaccines with 200 million doses spare

“We have got 200 million doses of stock. We had to shut down production in December,” Serum’s chief executive officer Adar Poonawalla said at the India Economic Conclave organized by Times Network on Friday, saying he was worried about wastage if the shots expired. “I have even offered to give free donations to whoever wanted to take it.”

Serum Institute of India Ltd., the world’s largest vaccine manufacturer and a key supplier of Covid-19 inoculations to developing countries, has stopped making fresh batches of shots after its stockpile grew to 200 million doses amid a global supply glut.

“We have got 200 million doses of stock. We had to shut down production in December,” Serum’s chief executive officer Adar Poonawalla said at the India Economic Conclave organized by Times Network on Friday, saying he was worried about wastage if the shots expired. “I have even offered to give free donations to whoever wanted to take it.”

Serum’s predicament underscores the vaccine oversupply that has crept up across a world once desperate for immunization against the coronavirus. Vaccine makers invested in massive production capacity over the past year and some of that has come online only after most countries covered much of their populations with two doses. The global adjustment to living with the virus -- with the exception of Covid Zero-practising China and Hong Kong -- has also diluted the urgency for booster shots.

The about-turn is especially stark in India, which just a year ago slapped an export ban on Serum and other local producers to ensure enough supply for the local population. The country now allows all those above the age of 18 to take booster shots, and Poonawalla urged wider expansion. He said that the government is also expected to cut the recommended time gap for a booster shot to six months after the second dose, from nine months now.

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.
