Bharat Biotech not allowed to conduct simultaneous Phase I, II trials for its intranasal COVID-19 vaccine

The SEC has reportedly refused to consider Bharat Biotech’s request and said it wants the Indian vaccine maker to first conduct the phase I trials and submit the immunogenicity data before moving on to the next stage.

Bharat Biotech has not been allowed to conduct simultaneous phase I and phase II trials for its nasal COVID-19 vaccine candidate, reported CNBC-TV18 on January 19.
The Subject Expert Committee (SEC) of the Central Drugs Standard Control Organization took the decision in a meeting called on January 19 for the approval of the phase I trial of the intranasal coronavirus vaccine being developed by Bharat Biotech in collaboration with the Washington University School of Medicine and Ocugen – a vaccine maker based in the US.

Bharat Biotech has claimed that the non-invasive, single-dose vaccine will be far easier to administer and will be an eco-friendly vaccine that will work faster and last longer.

Krishna Ella, Chairman, Bharat Biotech, has said: “An intranasal vaccine will not only be simple to administer, but will reduce the use of medical consumables such as needles, syringes, etc., significantly impacting the overall cost of a vaccination drive.”

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.

He had further said that “one drop of Bharat Biotech’s intranasal COVID-19 vaccine in each of the nostrils would be sufficient”.
