Ocugen Inc., Bharat Biotech's partner for USA and Canada for COVID-19 vaccine Covaxin on Friday said it has submitted a request to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of the jab for paediatric use.

The submission is based on results of a Phase 2/3 paediatric clinical trial conducted by Bharat Biotech in India with 526 children 2-18 years of age, which bridged immunogenicity data to a large, Phase 3 safety and efficacy clinical trial in nearly 25,800 adults in India, Ocugen said in a regulatory filing.

"Filing for Emergency Use Authorization in the U.S. for paediatric use is a significant step toward our hope to make our vaccine candidate available here and help combat the COVID-19 pandemic, Shankar Musunuri, Chairman of the Board, Chief Executive Officer and Co-Founder of Ocugen said.

Some research suggests that people are seeking more choices when selecting a vaccine, especially for their children.

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.
