Pune-based Gennova Biopharmaceuticals, whose mRNA Covid-19 vaccine GEMCOVAC-19 got the nod from the Drug Controller General of India, said on June 29 that the company was working on a booster dose that would be effective against the omicron variant as well.

Gennova Chief Operating Officer Samit Mehta said the clinical trial protocol for the booster shot has been submitted". “As far as the booster goes, we already have a candidate ready that will also address the omicron variant in addition to delta. We have made minor tweaks in the current formulation, and we have already submitted that protocol for clinical trials for boosters,” Mehta told mediaperson on June 29.

Gennova’s GEMCOVAC-19, India’s first home-made mRNA jab, is a thermostable vaccine and can be stored between temperatures of 2 to 8 C, which makes it favourable for deployment in India and other developing nations, as it can be transported to the most remote parts easily.

In contrast, mRNA vaccines made by Pfizer-BioNTech and Moderna need to be stored at sub-zero temperatures, which remains a challenge in lower and middle-income countries.

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.
