Here the authors develop a mucosal SARS-CoV-2 vaccine and show immunogenicity and protection in mice as well as reduced virus transmission in hamsters. This protein vaccine consists of a stabilized spike protein fused to monomeric IgG Fc, supporting its transport across epithelial barriers by binding to the neonatal Fc receptor.
