New Delhi: As the COVID-19 pandemic seems to be never-ending, scientists are working on next-generation vaccines and the top health expert said that a lot of efforts are on within the country for the development of vaccines.
According to Dr NK Arora Chairperson of COVID-19 working group NTAGI, "This whole concept of next-generation vaccine is that we don't have to give repeated doses. The second is if we give the vaccine it covers the prevailing viruses and also future viruses better and the protection remains for a long time."
