India has been seeing a downward trend in the number of new daily coronavirus infections. Most states are currently reporting fresh cases in the hundreds or in two-digits, with the exception of Maharashtra and Kerala.

While the number of daily cases being reported in Maharashtra has declined considerably, it is still remarkably higher than the rest of the nation. Similarly, in Kerala, which had once set an example for effective COIVD-19 management, daily coronavirus infections are still being reported in the thousands.

As per data shared by the Union Ministry of Health and Family Welfare, together, these two states account for 71 percent of the total COVID-19 caseload of the past week.

Out of a total 80,536 fresh cases being reported last week, 56,932 came from Kerala and Maharashtra; of this, 39,260 cases came from Kerala alone.

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.
