Open up licensing to develop vaccines and accelerate vaccination drive, demand medical experts

Companies other than Bharat Biotech must be given contracts to manufacture the indigenously developed Covaxin in bulk. This is the time to open licensing to any company that wants to produce vaccines and for anyone who wants to take a jab, per doctors.

The trillion-Rupee question haunting COVID-19-ravaged India today is this: why are companies other than Bharat Biotech [Bharat Biotech International or BBIL] not been given contracts to manufacture the indigenously developed Covaxin in bulk?

After all, that should have been the natural response of any government, instead of continuing with a tiny, 12.5-million-doses-a-month that the Hyderabad-based Bharat Biotech is coughing out at the present movement.

It hardly needs a rocket scientist to calculate that India, now the second worst-hit nation by the COVID-19 pandemic after the US, as some naysayers had dourly predicted earlier, is in dire need of mass immunisation, perhaps the biggest the world has ever seen, if it is to counter the COVID tsunami, not just the Second, but potentially a Third Wave as well.

The ability to carry out the world’s largest mass vaccination exercise in record time will depend on keeping vaccine supplies of hundreds of millions of doses flowing uninterruptedly for months.

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.
