BVDV vaccines are designed to protect cattle from Bovine Viral Diarrhea Virus (BVDV), a significant pathogen that can cause severe health issues in livestock. These vaccines help prevent the spread of the virus, which can lead to respiratory problems, reproductive failures, and even death in infected animals. There are two main types of BVDV vaccines: modified live vaccines and inactivated (killed) vaccines. Modified live vaccines stimulate a strong immune response, while inactivated vaccines are safer for pregnant animals. Regular vaccination is essential for maintaining herd health and productivity in cattle farming.
