Health Minister Harsh Vardhan: No community transmission in India; following all standards for COVID-19 vaccine development

Union Health Minister Dr. Harsh Vardhan has reiterated that there is no community transmission of the novel coronavirus in India, in the current situation.

Speaking to CNN-News18, Harsh Vardhan said that there is no permanent definition of the term ‘community transmission’. “There was some localised transmission in places like Dharavi (in Mumbai), but it was effectively contained,” he said.

He asserted that all mathematical predictions by experts on number of COVID-19 cases and mortality rate in India had been proven wrong.

The union health minister also said that the notice by the Indian Council of Medical Research (ICMR), pushing for fast tracking of a COVID-19 vaccine candidate was “misinterpreted”.

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.
