Confirmed COVID-19 cases in India have crossed the five lakh-mark. To be precise, India has so far reported 5.28 lakh cases of COVID-19, a disease caused by the novel coronavirus. This includes over 16,000 deaths, according to latest data from the Union Health Ministry.

There are only three countries, the United States, Brazil and Russia, that have reported more cases. At this growth rate, India is expected to cross Russia, which has reported 6.2 lakh cases, in a week's time.

The government is still differing on declaring the spread of the virus as community transmission. However, Goa Chief Minister Pramod Sawant has gone on record saying that community transmission has begun in his state.

The term ‘community transmission’ is used when it is difficult to trace a case back to a carrier or source.

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.
