Can vaccines cause autoimmune diseases?
Vaccines themselves do not cause autoimmune disease, but in genetically predisposed animals they may trigger autoimmune responses followed by disease – as can any infection, drug, or a variety of other factors. 21. May I split vaccines in combination products? Yes – For example, Leptospira bacterins are often the diluent for the viral antigen combination. The “viral cake” may be resuspended in sterile water, and the Leptospira bacterin be given separately at another site or time, or discarded. 22. Will a single vaccine dose provide any benefit to the dog or cat? Will it benefit the canine and feline populations? Yes – One dose ofa MLV canine core vaccine (CDV, CPV-2 CAV-2) or a feline core vaccine (FPV, FCV, FHV-1) should provide long term immunity when given to animals at or after 16 weeks of age. Every puppy and kitten 16 weeks of age or older must receive at least one dose of the MLV core vaccines. If that were done, herd (population) immunity would be significantly improved. Even i
