In today's VETgirl online veterinary CE podcast, we discuss the potential development of an autoimmune response against platelets following live virus infection from canine influenza, and separately following vaccination with distemper (DA2PP) vaccine. Have you ever wondered before in your immune-mediated thrombocytopenic patients whether or not recent vaccination could have been the inciting factor for this autoimmune condition? Well, Williams et al. sought to get us the veterinary evidence that can tell us if viral infection or vaccination can cause this autoimmune dysregulation in our canine patients as described in their article entitled “Effects of Canine Influenza Infection and DA2PP Vaccination on the Development of Platelet-Associated Immunoglobulins and Platelet Counts in Dogs.”
