Bharat Biotech’s coronavirus vaccine Covaxin will now enter phase II of clinical trials. The firm developing India’s indigenous vaccine candidate for COVID-19 secured the Centre’s nod to begin phase II trials on September 3.

The phase I trials of Covaxin reportedly went as per expectations, with no side-effects being reported in volunteers who were administered the COVID-19 vaccine shots. During the first phase of the trials, 375 people across the country were given Covaxin shots.

As per the letter issued to Bharat Biotech International by Dr S Eswara Reddy, the Joint Drugs Controller of India, phase II clinical trials of the BBV152 coronavirus vaccine, or Covaxin, will be conducted on 380 volunteers. All participants will now have to be screened for four days after they are administered the vaccine shots.

The letter further mentions that the Central Drugs Standard Control Organisation (CDSCO) under the Directorate General of Health Services, Ministry of Health and Family Welfare, “has no objection for conducting the trial titled ‘An adaptive, seamless Phase I, followed by Phase II randomized, double-blind, multicenter study to evaluate the safety, reactogenicity, tolerability and immunogenicity of the whole-virion inactivated SARS-CoV-2 vaccine (BBV152) in healthy volunteers’.”

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.

Twelve medical centres have been chosen by the Indian Council for Medical Research (ICMR) to conduct the human clinical trials of the vaccine developed by Hyderabad-based Bharat Biotech.

Apart from Bharat Biotech, Zydus Cadila is the other Indian company that has begun human clinical trials of its vaccine candidate. Meanwhile, phase II human trial of the COVID-19 vaccine produced by the Pune-based Serum Institute of India has begun at the BJ Medical College. This vaccine is being developed by Oxford University and Swedish-British drugmaker AstraZeneca.
