The government is preparing for a second wave of coronavirus infections to hit India in late May or early June as restrictions begin to ease and the government starts "gradual" lifting of the lockdown, sources told The Indian Express.

The government is also hoping that post-May 3, the doubling time of the cases would have increased to 12 days. The Health Ministry on April 20 said the doubling time is now 7.5 days, an improvement from 3.4 days before the lockdown was imposed.

According to the newspaper, the government is hoping that the rate of doubling would increase to 10 days by the end of this week and 12 days by the first week of May.

"... But after that, as we gradually start to open up — the lockdown will definitely not be lifted in one go — there will be a gradual increase (in cases)," a source told the newspaper.

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.
