Six Indian cos working on Covid-19 vaccine; ramp up testing, say experts

As Covid-19 infects more than 1.9 million in the world and claims 1,26,000 lives, Indian scientists are also part of the global fight against the disease

Six Indian companies are working on a vaccine to control coronavirus, joining global efforts to find a quick prevention for it, a top Indian scientist said.
