Will Coronavirus Vaccines Be Effective Against the Strain from India?

The world has a new coronavirus mutant spreading from one continent to another — and it looks like a tough one to stop.
The World Health Organization declared Monday the variant that emerged in India, known as B.1.617, is officially a “variant of concern.”
“There is some available information to suggest increased transmissibility of B.1.617,” the WHO’s Marie Van Kerkhove said Monday from Geneva. Last week, NPR published a story explaining why B.1.617 could be the fastest-spreading mutant on the planet.
