Vaccinations in Veterinary Medicine: Dogs and Cats: Vaccinosis
Dr. Michael W. Fox DVM - "Adverse vaccination reactions resulting in disease (so called vaccinosis) include injection-site fibro- sarcomas in cats, and various immune-system dysfunction diseases, possibly hyperthyroidism, inflammatory bowel disease, various chronic skin conditions and kidney disease. More research has been done in dogs, where certain breeds and lines are particularly prone to develop vaccinosis.
Conditions associated with same include encephalitis, seizures, polyneuropathy ( weakness, incoordination and muscle atrophy), hypertrophic osteodystrophy (shifting lameness and painful joints), autoimmune thyroiditis and hypothyroidism, liver, kidney and bone marrow failure variously associated with autoimmune hemolytic anemia, immune mediated thrombocytopenia." more
