The Purdue Vaccination Studies and Auto-antibodies
A team at Purdue University School of Veterinary Medicine conducted several studies (1,2) to determine if vaccines can cause changes in the immune system of dogs that might lead to life-threatening immune-mediated diseases. They obviously conducted this research because concern already existed. It was sponsored by the Haywood Foundation which itself was looking for evidence that such changes in the human immune system might also be vaccine induced. It found the evidence.
