New grasp of key COVID-19 protein may lead to a live-attenuated vaccine effective against more variants for longer

Researchers have identified a key protein in SARS-CoV-2 that, when targeted, elicits a robust immune response. A live-attenuated vaccine based on this protein shows promise in preventing disease and offering long-lasting immunity. The approach could target areas of the genome less likely to change with variants.
