The Centre on April 8 shot letters to five states which had reported a rise in COVID-19 test positivity rate during last week, when compared to the previous week, and asked them to keep an eye on the clustering of cases.

In separate letters written to Kerala, Maharashtra, Delhi, Haryana and Mizoram, Union health secretary Rajesh Bhushan also pointed out that they are reporting a higher number of daily coronavirus cases as compared to others.

The letter written to Kerala highlighted that it has reported 2,321 new cases in the last week ending April 8, accounting for 31.8 percent of India’s new cases while the test positivity rate has risen from 13.45 percent to 15.53 percent.

In the communique sent to Mizoram, Bhushan pointed out that the state had registered 814 new cases last week, accounting for 11.16 percent of India’s new caseload while the test positivity rate rose from 14.38 percent to 16.48 percent.

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.
