Purdue Studies Show Vaccinated Dogs Can Develop Immune-Mediated Diseases

Story Highlights
  • 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.”

  1. I had a dog who died of haemolytic anemia about 9 yrs ago (Rottweiler, 9 yrs old and healthy). He was recently vaccinated, and suddenly fell ill and died within 4 days. I am an RN and was researching this. Discovered the link between vaccines and haemolytic anemia as well as heartworm med, flea topicals, etc.

    Now, my dogs get all their puppy shots and their rabies every three yrs (only because it is required by law). No heartgard, no topicals. No fleas, no ticks (I use natural based products). They are very healthy.

    I am so surprised that many vets still push the annual vaccines (including mine!). People have to be more proactive with their furry kids and their human ones too! Don’t always take the vets/doctors word as gospel, do research!

    1. Freda,
      Take it to the next level!

      Stop all vaccines! The reason they now inject into the shoulder is because they can amputate the shoulder and animal survives when they develop cancer there! They used to inject at the spine. You can still survive legally without the vaccines except for rabies. Nobody will report. Your vet may have you sign a release in their office to continue treatment for other stuff, but if you don’t vaccinate them, why do you need the vet. Emergencies only.

  2. If you’re going to have your dog vaccinated for rabies, you might as well give him all the rest of them, as well. Rabies is probably one of the most offensive vaccines ever developed.

    Just say no.

  3. I and my husband got a 5 year old, 8 pound toy poodle from the shelter. They gave him one year shots when we got him. Rabies, distemper and Bordetella (kennel cough-similar to whooping cough). One year later I took him to the vet for the shots. He was given a 3yr rabies and 3 yr distemper vaccine. That night he had his first seizure. He foamed at the mouth and his legs went out from under him. His eyes could not focus. Since it was 8 at night the vet was closed and I had to take him to an animal hospital. The vet there gave him a cortisone shot but at that point the seizure had stopped. The seizure lasted an hour. The seizures started at once a month and progressed to 2 x a week. The vet put him on Phenobarbital and he has been on it ever since (7 years). He has been to 3 vets and only one would admit that his brain was overstimulated from the shots. No one could convince me at this point that the vaccines did not do this to him.

  4. Hi guys, on the Purdue studies, I can’t find the main references 1 & 2. They are cited numerous times but none of the links work. Can anyone find working links to the material? I’m hanging out to dry on a few posts. Keep up the good work, thanks.

      1. Yes, all the traces back to the purdue study are not working. Does anyone have a link to the paper?

  5. To write an article referencing studies and not produce documentation of the study itself is a serious flaw in the legitimacy of this article. The Article states:

    “The vaccinated, but not the non-vaccinated, dogs in the Purdue studies developed autoantibodies to many of their own biochemicals, including fibronectin, laminin, DNA, albumin, cytochrome C, cardiolipin and collagen.”

    While the letter may be legit, the article makes a number of specific claims about ongoing studies and fails to cite them. When I passed this along, I got slammed. I guess I deserved it for not researching this stuff myself. NVIC needs to maintain high integrity on published material. When they don’t The shills win hearts and minds.

    1. Just FYI, upon my own research due to the death of my dog due IMHA and after her 11th does of DHPP, I started researching. Found a revised 2009 vaccine schedule which was public at the time and confirmed the above. Three months later, the article was removed from public library and placed in student only library. I called Purdue, was able to get view only abilities. I took a picture and this post won’t let me share it here. If you email me at [email protected], I will send you a copy.

  6. STOP testing on animals, Beagle Freedom Project is working to free dogs that are being tortured in laboratories across the United States, apparently Purdue University School of Veterinary Medicine is using beagles for research and violent testing. None of this is necessary if they tested on prisoners. These dogs live in cold cages with no human touch other than cruelty. Stop the cruelty! These dogs get no compassion, only pain. They are injected, tested, tubes shoved down the throats and tortured daily by sick, uncaring researchers. Please do not support animal research.

  7. Post this instead as my previous had errors:
    I only give my dog bordatella when she goes to the kennel and it has been over six months, but am interested in what others do naturally to ward off fleas? My vet said diatomaceous earth does not work even though I had already used it.

    1. Blake:

      My comment is being reviewed prior to posting so this may not appear. However, as an effort to help you and prevent unnecessary meds given to your animal I’ll suggest you read my post about Diatomaceous Earth.

      As for protection whilst in a kennel…check out Vitality Science (the website name). The offer remarkable forward thinking immune support and other formulas for cats and dogs.

      Over many years and after living with many rescued dogs and cats who lived vaccine free to the age 17 for the dogs and 20 for the cats, here are the methods I used:

      Brewer’s Yeast and/or garlic added to wet food or,if the animal likes it, sprinkle a bit on top. Red Star seems to work and they like the flavor (flaked variety)

      Pennyroyal oil soaked into either cotton clothes line and tied around their neck or a bandana. Fleas and ticks are repelled by both scents.

      Diatomaceous Earth added to their food and also rubbed into their skin works very well. Farmers douse chickens in it by dropping them into sacks full and shaking the sack.

      If you ever wonder about the safety of a med…be responsible animal guardian and go online to find the info. It’s how I learned these methods.

      Best of luck

    2. Diatomaceous earth does work to repel fleas and other parasites. My golden retriever has never had a flea. He also has never had parasites found in his annual stool samples.

  8. Regarding diatomaceous earth and Vets who diss it: D.E. (human grade) was the only thing that removed a tape worm from a cat I rescued.

    She was examined and treated for worms at my Vet. Then was spayed and subsequent second treatment…both meds tried, neither worked.

    He tummy was seriously distended, her appetite was insatiable because the tapeworm was ingesting the food and leaving little or none for her.

    I began adding D.E. to her food….within a few days, her litter visits declined, her appetite lessened and after 3 weeks she passed the tape worm in her litter box and has been totally healthy since then. Most Vets only know what the drug salespeople tell them. Holistic Vets are better informed and much more willing to listen and learn.

    There’s also a new product called ‘FleaNoMo’…google it. Totally safe for animals…vegetable based, no dangerous neurotoxins like Frontline and others. It kills fleas and ticks by causing their exoskeleton to crack and exposes their organs which brings on death. D.E. does the same. Also brewers yeast sprinkled on wet food for animals will change the animals scent and make it less desirable for fleas and ticks.

  9. For years my dogs itched from spring to fall, I refuse to use toxic flea meds, until I tried a natural non-toxic cedar spray. It works wonderful and they did not suffer from scratching last year since I started using it. I’ve tried DE, essential oil flea spray, none of that worked for us.

  10. This is nothing new! Dr. Ron Schultz from the Univ of Wisconsin has been saying the exact same thing since at least the late 1970’s! My “regular” vet in MN told me that! He’s been doing vaccine research for more than 40 years and has been saying that the puppy and kitten vaccines confer immunity for AT LEAST 5-7 years (the length of the study at that point) and most likely for the lifetime of the animal. He is the reason why the AAHA and AVMA FINALLY went to a 3 year recommendation for vaccines. Vets that are still doing annual vaccines are onoly , IMO, doing it for the extra income that the vaccines, exam visits and illness visits cause. I just read an article about a poor 1.5 yr old pit puppy who died after receiving his vaccines. So sad that vets aren’t more “up” on these things! It’s up to pet parents to help push the “old school” vets into this century!!

  11. Pennyroyal oil was once used to control fleas on pets, but no longer. We now know that, whether it’s applied to the skin or ingested, pennyroyal oil is toxic to cats and dogs. … When pennyroyal oil is applied to the pet’s skin, dermatitis can occur. A more serious side effect is liver damage
