Nanoparticle Vaccine Technology Introduces Immune System to a Variety of Different Coronaviruses

This new vaccine prototype works by attaching many protein fragments (specifically, receptor-binding domains or RBDs) to an engineered protein-based nanoparticle. The study, in mice, showed that the vaccine induced the production of antibodies that are broadly reactive to a wide range of coronaviruses. RBDs are particularly important for a virus to be able to infect a cell, so antibodies that recognize RBDs are likely more effective at preventing bad infections. Credit: Courtesy of A.
