Coronavirus pandemic | India's migrant workers fall through cracks in COVID-19 lockdown

But now a hush has come over the clattering construction site, silenced by India's nationwide order to shelter in place to prevent the spread of the novel coronavirus. Site managers no longer come to the intersection where Dayaram and many others stand, hoping to pick up work.

Most days, you can find Dayaram Kushwaha and his wife, Gyanvati, hauling bricks for stonemasons in a booming northern suburb of New Delhi. They bring their 5-year-old son, who plays in the dirt while they work.

But now a hush has come over the clattering construction site, silenced by India's nationwide order to shelter in place to prevent the spread of the novel coronavirus. Site managers no longer come to the intersection where Dayaram and many others stand, hoping to pick up work.

And so, with no way to feed his family or pay the rent, Dayaram hoisted his son Shivam onto his shoulders and began to walk to the village where he was born, 300 miles away.

He tried not to worry about what would happen once he got there, with empty pockets instead of the money he usually sent home to help support those left behind. At least he would have a home.

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.
