Vaccinations and Canine Cancer


There is little that can annoy me more than hearing about a dog with cancer that has gotten a vaccination. And it happens every day.

Please make no mistake about it. If your dog has cancer it is imperative that they never receive another vaccination. Not ever again for the rest of their life. There are clear warnings about this from the pharmaceutical companies who make the vaccines. Any vaccination given to your dog will further impair their immune system and greatly reduce their likelihood of recovery.

Now, you may be saying, “But where I live, the law says I have to get my dog vaccinated.” The fact is, in most jurisdictions, this only applies to healthy dogs. Where I live, I can get an exemption from vaccinating my dog if she is unhealthy. And the same is true in most jurisdictions. All I need to do is to get my vet to write a letter that says because of my dog’s health problem, she should not be vaccinated, and send it to the county. You can search the internet to find out what the animal vaccination laws are where you live. In most places, you will find the law allows the same exemption.

In cases where your vet wants to vaccinate you dog with cancer, or  refuses to give you a letter, you may want to consider getting a new vet. Here’s why.

Every dog vaccine has a statement on the label and in the package insert that says this, or something similar to it. “For the vaccination of healthy dogs against _______ (whatever the vaccination is for).” Well guess what? Your dog has cancer and because of this, is not healthy. According to the manufacturers instructions, vaccinations are not supposed to be given to unhealthy dogs!

Here’s another example in a rabies vaccination insert from a major pharmaceutical company. Under precautions it states, “This product has been shown to be efficacious in healthy animals.” This means it has NOT been shown to be efficacious in unhealthy animals!

It goes on to say, “A protective immune response may not be elicited if animals are incubating an infectious disease, are malnourished or parasitized, are stressed due to shipment or environmental conditions, are otherwise immunocompromised, or the vaccine is not administered in accordance with label directions.”

If your dog has cancer he/she is immuno-comprimised, and it is not safe to give him/her a vaccination.  And by definition, your dog is physiologically stressed because of the cancer.

I could go on ad infinitum about the potential and real dangers of vaccinations, not only for dogs with cancer, but for all dogs. I have a list of diseases that are caused by vaccinations in Dog Cancer: The Holistic Answer.

Just remember. If you dog has cancer…NO VACCINATIONS!

    Wish I had known this back in the nineties. My girl had bone cancer. She was in a remission when it came time for her annual rabies vaccs. The vet saw her leg and commented on the cancer. Then he gave her the shot. Almost immediately, the tumor started growing again. She passed within 4 months of that shot. Lacey passed in July of 2000, well after the duration of immunity study was published.

    Dr. Eisen,,
    I wish I had received this information before I took my beloved Benjamin to the vet. He already had a degenerative condition and I was hesitant to get him vaccinated and told that to my vet. But the vet went ahead and vaccinated him anyway. Three months later Benjamin was diagnosed with bone cancer. I know the vaccination caused this, but my vet would not admit it. My boy broke his leg last week and had to be euthanized. I feel angry and guilty and am so glad you are telling others about this.
    Thank you.

    What are the ramifications for the dog with cancer if they were vaccinated?

  4. Steve H says:

    Linda I would like to know about your dog’s cancer case. How did it go into remission? What was age breed at time of diagnoses and treatment,etc. My 8 yo german shorthair pointer has just been diagnosed with osteosarcoma and I am looking into holistic and conventional treatments.Conventional says amputate but i really don’t want to do that. Thanks in advance.

  5. Vaccinations significantly lessen a dog with cancer’s chance for survival as they impair the immune system and contain carcinogens.

    Dr. Eisen,

    We have a 13 year olf Goden. She has a tumor on her skull under 3 layers of muscle. They just did some minor surgery yesterday to get a sample from that tumor to conduct a biopsy. I will simply assume at this point that it is malignant. But we will get the final results Monday. Anyway, I came across your site yesterday and saw your second video on diets for cancer dogs. Paticularly the recipe you made with the beef and vegetables.

    Anyway, my question is this. Wouldn’t it be too late at this point to switch diets? Particularly if the Dr. tells me the tumor is malignant and it will be fast growing?

    Thank you.

  8. That’s exactly why you should switch. It’s never too late.

    Dr. Steve

    I had my beloved Doberman, diagnosed with bone cancer in Jan 2012, prior to that, our old vet (who has since retired) treated her with an months of steroids both oral and injected. He retired, and the new vet went another direction and referred us to an oncologist who quickly told us our options. We had her rear leg amputated and she recovered nicely. Since she was doing well, we decided it would be okay to kennel her for 4 days while we went on a vacation. When we returned, we were told that our vet had been gone, and the old vet (who had retired and missed her diagnosis) had covered during that time for her, he gave her Rabies, Bordatella, DHPP, and Leptospirosis, 4 vaccines on on a dog who was doing great, since then, it’s been 3 weeks, she has had diarrhea, lethargy, and 2 courses of antibiotics, she is in organ failure and we plan to have her put down tomorrow in our home. I feel responsible as I should have known, but you entrust your family to the medical experts, and they sometimes are all about money, not the best interest of the pet. We are devastated and wish we would have known. If we would have ever thought she wasn’t in good hands, or had we known our vet was going to be gone we would have never left her. I only hope the word gets spread so others know the risk of vaccines in pets with cancer.
