Prolonged Omicron-specific B cell maturation alleviates immune imprinting induced by SARS-CoV-2 inactivated vaccine
3 Oct 2024
Abstract excerpt
SARS-CoV-2 ancestral strain-induced immune imprinting poses great challenges to updating vaccines for new variants. Studies showed that repeated Omicron exposures could override immune imprinting induced by inactivated vaccines but not mRNA vaccines, a disparity yet to be understood. Here, we analyzed the immune imprinting alleviation in inactivated vaccine (CoronaVac) cohorts after a long-term period following...
