Abstract
Currently, to validate efficacy of BVDV vaccines, clinical trials commonly involve challenge of vaccinates with a single intranasal inoculation of a BVDV field strain. Licensed vaccines provide nearly complete protection (91 to 100%) of dams and developing fetuses after this artificial challenge. However, exposure to animals persistently infected (PI) with BVDV may better represent viral challenge under field conditions. The objective of this research is to assess the efficacy of vaccination for control of bovine viral diarrhea virus (BVDV).
