When Dharavi in Mumbai reported its first case of COVID-19 in early April, experts had warned that the densely populated region, known to be Asia's largest slum, could fast become a major hotspot — not just in the Maximum City, but also the country.

The experts were right. Dharavi became a COVID-19 hotspot quickly as infections in the area began to rise. It remained one of the worst-affected regions in the worst-affected city in India. But come June, Mumbai's civic body, the Brihanmumbai Municipal Corporation (BMC), has managed to turn things around a bit.

"COVID came to Dharavi with a death," says Kiran Dighavkar, Assistant Commissioner of G-North ward and the official who has been leading the fight in Dharavi from the front. Dighavkar was referring to the first case in Dharavi, when a 56-year-old man died due to complications from the disease.

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.
