Abstract: Compositions, and methods of preventing Measles and other viral infections using the compositions, related to single-chain variable fragment- (scFv-) based antivirals that bind to the measles virus (eV) F peptide and block F-mediated membrane fusion, thereby preventing infection. The scFv may interact synergistically with MeV fusion inhibitory peptides, such as HRC4. The scFv may be administered to the patient by airway, such as intranasally, and may be co-administered with one or more MeV fusion inhibitory peptides, such as HRC4.
