Union health minister Mansukh Mandaviya, on June 23, chaired a high level meeting to review status of COVID-19 in the country and directed officials to focus on surveillance and genome sequencing, apart from monitoring hospitalization.

He also urged for ramping up testing and accelerating COVID-19 vaccination of eligible population.

The meeting entailed a detailed discussion on global scenario of surge in COVID-19 cases and status of infection in the country.

This included presentation and analysis of trend of COVID-19 cases, daily and active cases, positivity and deaths, testing status along with state-wise weekly tests per million, RT-PCR share in weekly tests, genome sequencing apart from vaccination status.

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.
