Using llamas immunized with prefusionstabilized betacoronavirus spike proteins, Wrapp et al. identify neutralizing cross-reactive single-domain camelid antibodies, which may serve not only as useful reagents for researchers studying the viruses causing MERS, SARS, and COVID-19, but also potential therapeutic candidates. Crystal structures further reveal how these antibodies bind spike proteins to prevent virus entry into cells.
