Abstract
Rabbit hemorrhagic disease virus (RHDVb) is the new variant of the classical RHDV, a virulent pathogen responsible for an acute disease in young rabbits. The virus invades internal organs, especially the liver, spleen, kidneys, and gut; prevents coagulation; and causes liver necrosis. This eventually leads to quick death of the animal because of hemorrhage. In this study, we evaluated the effects of a new vaccine against RHDVb in rabbits at a young age, after experimental infection using four different viral isolates. Our findings show that the vaccine had a protective effect with survival rates reaching 80–100% against the different isolates. These results suggest that this vaccine, when applied to young animals, is an effective tool to protect against the disease caused by RHDVb in rabbitries.
