title: Onset of protection from experimental infection with type 2 bovine viral diarrhea virus following vaccination with a modified-live vaccine.
abstract: The onset of protection after the administration of a modified-live bovine viral diarrhea virus (BVDV) vaccine was determined. Protection was determined following experimental infection with a virulent type-2 BVDV (strain 1373) in cattle vaccinated 3, 5, or 7 days before BVDV infection. Protection, as measured by reduced virus shedding, lack of leukopenia, reduction in viremia, and reduced mortality, was present as early as 3 days after vaccination with a single dose of modified-live BVDV vaccine. Complete protection was obtained in cattle vaccinated 5 or 7 days before BVDV experimental infection.
