The moves show a growing realization that the vaccine nationalism many wealthy nations have embraced has the potential to backfire, prolonging the global pandemic. While those countries have been cornering supplies of the first vaccines for their world-leading rollouts, places like India have run short, allowing the virus to run wild. Some scientists have linked the nation of 1.3 billion people’s second wave to a more virulent strain, with the out-of-control outbreak providing a petri dish for further mutations to evolve that could challenge the vaccines now being distributed from the U.K. to Israel.
“There is certainly potential for new variants to emerge in a country the size of India that could pose a threat elsewhere,” said Ramanan Laxminarayan, founder of the New Delhi and Washington-based Center for Disease Dynamics, Economics & Policy. “It is in the world’s interest to ensure that India exits the pandemic at the earliest, and vaccination is the only way.”
