Swiss researchers launch trial for COVID "patch" vaccine

Swiss medical researchers said on Wednesday they have launched an early-stage study to test a next-generation COVID-19 vaccine candidate which would be administered via an arm patch, the latest to look at alternative methods of giving injections. Unlike conventional vaccines that stimulate antibody production, the new PepGNP-Covid19 vaccine candidate focuses on T-cells, which are responsible for cellular immunity, to eliminate cells infected by the virus and prevent it from replicating.
