Here, we identified two potent, neutralizing single domain antibodies directed against the tetrameric receptor binding (H) protein of CDV. Structural analyses spotlighted two vulnerable sites within the H protein. While the first overlaps with the receptor binding site, the second encompasses amino acid residues of two protomers located at the distal dimeric head interface, which supports distinct mechanisms of neutralization. Upon application of an engineered tetravalent and biparatopic antibody, ferrets were protected at a remarkably low antibody dose (1 mg/kg) administered intra-peritoneally on days 3 and 7 post-exposure of a lethal CDV challenge. Collectively, this study spotlights the power of integrating multiple mechanisms of neutralization in a single format and provides a roadmap to design next-generation therapeutics against morbilliviral infections as well as other infectious pathogens. |
