NEW DELHI : Scientists have identified regions of the SARS-CoV-2 virus that causes COVID-19 to target with a vaccine, by harnessing tools used for the development of cancer immunotherapies.The researchers at Children's Hospital of Philadelphia (CHOP) in the US employed the same approach used to elicit an immune response against cancer cells to stimulate an immune response against the novel coronavirus.Using this strategy, the researchers believe a resulting vaccine would provide protection across the human population and drive a long-term immune response."In many ways, cancer behaves like a virus, so our team decided to use the tools we developed to identify unique aspects of childhood cancers that can be targeted with immunotherapies and.
