Our objective was to evaluate whether porcine reproductive and respiratory syndrome virus (PRRSV) vaccination improved mortality and morbidity following experimental infection with a PRRSV restriction fragment length polymorphism 1-7-4. Results indicated that mortality and morbidity were significantly lower for vaccinated pigs as compared to unvaccinated pigs (P < .001).
