Lockdown stringency in India rises, among strictest in the world now

Including partial lockdowns, nearly 80 percent of the economy is now subject to substantially tighter COVID restrictions, said an Oxford Economics report.

Before daily COVID-19 cases started tapering earlier this week, there were multiple calls for a national lockdown to contain the lockdown. This was despite states starting to impose strict curbs starting in April.

How do these curbs compare to the national lockdown of a year ago?

One way of gauging that is to look at the Oxford Coronavirus Government Response Tracker which measures the strictness of a government’s policy responses towards COVID-19 based on a Stringency Index that calculates the mean score of nine policy measures (such school closures, workplace closures, stay-at home requirements and travel bans), each taking a value between 0 and 100.

A higher score indicates a stricter government response with 100 being the strictest on the scale.

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.
