At a time when the world is looking for a breakthrough to tackle the spurting cases of COVID-19, this Chennai and Palo Alto-based startup is working on a non-invasive digital vaccine with an aim to curb the menace.

The role of a vaccine is to stimulate the immune system of an individual to respond and produce antibodies that will help in fighting the disease.

Digital vaccine, on the other hand, enables neuro-behaviour and physiological modulation to protect health at an individual and societal scale.

Launched in 2013 by Bhargav Sri Prakash, FriendsLearn was started as a life science research organisation. In 2019, it commercially launched its first digital vaccine for children under the brand name FOOYA in partnership with US-based Carnegie Mellon University. The vaccine works to lower the risk of lifestyle diseases such as diabetes, cardiovascular disease, hypertension and cancer.

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.
