Abstract: Provided are innovative compositions for tethering blocking an inactivating of airborne respiratory infectious viruses. The compositions comprise bispecific proteins with two different antigen binding regions (ABR), which are typically configured as immunoglobulin “single variable domains” (ISV). A first ISV binds to a surface protein found on an airborne infectious virus. A second ISV binds to a mucin protein, e.g. a mucin protein present on ocular, nasopharyngeal, tracheal and/or oral surfaces of a mammal. The two ISV are joined by a polypeptide linker.
