There has been a steady decline in the positivity rate of COVID-19 despite an exponential increase in testing, the Union Health Ministry said, underlining that the number of active cases of the infection have reduced by 6,423 in a day for the first time.

"Thirty-six per cent of the deaths have been reported in the age group between 45-60 years and 51 per cent deaths in people aged 60 and above. Eleven per cent deaths were reported in the age group of 26-44 years and 1 per cent each among people aged 18-25 and those below 17," he said addressing a press briefing.

The testing for the disease has been increased from 363 tests per million per day on August 1 to more than 600 tests per million per day at present, Bhushan said, with India having tested nearly 3.7 crore cumulative COVID-19 samples so far.

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.
