India has logged 27, 409 new COVID-19 cases in the 24-hour period with fresh infections 19.6 per cent lower than the preceding day and the lowest in more than 40 days.

With this, the tally of confirmed coronavirus cases in the country has reached 4,26,92,943.

The country now has 4,23, 127 active COVID-19 cases, 11.6 per cent lower than February 14 with a fall of 55,755 cases in day.

Kerala, which along with other states is also witnessing a rapid improvement in the pandemic situation, presumably triggered by the Omicron variant, reported a dip of 15,946 active cases in a day even though, at 1.45 lakh, it still has the biggest load of active infections.

Now it is the only state in India with over 50,000 active COVID-19 cases

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.
