COVID-19: Covovax to get approval as booster in 10-15 days, says SII CEO Adar Poonawalla

He said everyone was looking at India, not just in terms of healthcare but because the country managed to take care of a huge and diverse population and also helped 70 to 80 nations during the COVID-19 pandemic.

Serum Institute of India chief executive officer Adar Poonawalla on Sunday said its Covovax vaccine will get approval as a booster in the next 10 to 15 days, adding it works well against the Omicron variant of coronavirus.

Speaking to reporters on the sidelines of an event at Bharti Vidyapeeth University here, Poonawalla, when asked about states and districts not getting Covishield vaccines, said there are ample stocks with the Union government for supply.

"Covovax will be approved as a booster in the next 10-15 days. It is actually the best booster because it works very well against Omicron, more than Covishield," said Poonawalla.

He said everyone was looking at India, not just in terms of healthcare but because the country managed to take care of a huge and diverse population and also helped 70 to 80 nations during the COVID-19 pandemic.

"This was all possible because of the leadership of our Central government, our state governments, healthcare workers, manufacturers, all of whom worked together with one common goal," he said.

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.
