'Next gen' vaccines needed to tackle emerging variants: Scientists

Scientists believe that the spread of new Covid-19 variants is not an immediate problem, however, it's time to already work on next-generation vaccines as a preventive measure. And though the present vaccination drive will contribute to slowing the pandemic, next-generation vaccines will be needed to deal with the emerging new strain, the scientist from New Delhi’s National Institute of Immunology told PTI.
The variants found so far have undergone changes or mutations that mean they can infect human cells more easily than the original version of the novel coronavirus that started the pandemic.
