- Purdue University studies show that vaccines may cause life-threatening immune system disorders in dogs.
- Terminal cancers occurring at the vaccination site have been reported in cats and dogs.
- Many animals are genetically unsuited to withstand the effects of vaccines.
In an article published on the online magazine Dogs Naturally, Catherine O’Driscoll writes that research done at Purdue University School of Veterinary Medicine shows vaccines can lead to life-threatening immune-mediated diseases in dogs. O’Driscoll is founder of the nonprofit organization Canine Health Concern (CHC).
In studies conducted by Purdue, the vaccinated animals developed autoantibodies to many of their own cell structures, including fibronectin (involved in tissue repair), laminin (important to many cell activities), cardiolipin (a common finding with autoimmune disorders) and collagen (an important protein that provides underlying support to the body and soft tissues), as well as to their own DNA.
The American Veterinary Medical Association (AVMA) Vaccine-Associated Feline Sarcoma Task Force has also looked into why approximately 160,000 cats in the United States develop terminal cancers at the vaccination site—an effect common enough that cats are generally vaccinated in the tail or a leg to allow for amputation if tumors develop. Vaccine-site cancers have similarly been reported for dogs and humans.
Modified live virus vaccines have an acknowledged association with a fast-acting, generally fatal disease known as autoimmune haemolytic anaemia (AIHA), and additional research has linked polyarthritis and amyloidosis to a combination vaccine given to dogs. Referring to a substantial body of research confirming that vaccines can cause significant brain and central nervous system damage in dogs, including encephalitis and brain inflammation and damage, O’Driscoll quotes a letter by Dr. Larry Glickman, who led the Purdue research group:
Our ongoing studies of dogs show that following routine vaccination, there is a significant rise in the level of antibodies dogs produce against their own tissues. Some of these antibodies have been shown to target the thyroid gland, connective tissue such as that found in the valves of the heart, red blood cells, DNA, etc…
Just as in the human population, some animals are not genetically able to withstand the vaccine challenge and are likely to suffer an adverse reaction to vaccination. In individuals with faulty B and T cell function, for example, the immune system may overreact and lead to allergies and other inflammatory conditions such as arthritis, pancreatitis, colitis or autoimmune diseases.
All 27 veterinary schools in North America, as well as the American Veterinary Medical Association, have determined that annual vaccination is unnecessary, and that vaccines may cause harm. With change so long in coming, says O’Driscoll, “hundreds of thousands of animals are dying every year, unnecessarily.”
