Live vs Inactivated:
There are two types of IBR vaccines: live vaccines and inactivated vaccines. In terms of shedding of BHV-1 (IBR) virus in newly infected naïve animals, vaccinating with the live vaccine results in less shedding compared to the inactivated vaccine ˡ. However, several studies have shown that live IBR marker vaccines provide better protection against clinical signs than inactivated vaccines. Therefore, it is important to speak to your vet for more information on the advantages of live IBR marker vaccines. Vets can also provide guidance on which vaccination regime is most suited to your herd circumstances, ensuring optimal protection for your animals.
