The Cat Vaccine Hoax

Welcome to the “Healthier Cat Detox Series” Part Three

Have you ever wondered if yearly cat vaccines are really necessary and if they are doing any harm to your cat?

We vaccinate to protect our cats from diseases and viruses and because veterinarians tell us to do it.  Every year, we receive the vaccination reminder–“it’s time for your cat’s annual vaccination…keep your vaccines up to date…protect your cat…don’t risk your cat getting sick”…etc., etc., etc.. You dread the visit, your cat certainly dreads the trip to the vet, and you may even wonder if it’s really necessary. Your cat may have had a bad reaction soon after a previous vaccination, but the vet assures you it’s normal or the side effects are better than not vaccinating. Long ago, before I knew anything about this, I was routinely vaccinating my cats and dogs.

There is much evidence that repeated vaccines do cause reactions–sometimes soon after, weeks, months, even years later- and that they do weaken the immune system. The compromised immune system is then much more susceptible to other illness and diseases. And some cats even develop the very disease for which they were just vaccinated. In the feline 4-in-1 FVRCP, the vaccine does not provide immunity to rhinotracheitis and calicivirus (the R and C in FVRCP). The vaccine does supposedly assist in the severity of the symptoms should a cat become infected (but I can argue that, see next paragraph). The vaccine does reportedly provide immunity to Panleukopenia (or feline distemper).

It Happened to My Harmony

She was vaccinated as a young cat by a cat rescue group as part of the protocol, along with spaying. Six months later, she contracted herpes from a tiny foster kitten, who strangely enough came down with only a very mild cold and quickly recovered. The herpes virus went into her eyes, and one eye developed an ulcer which required sewing her eyelid up over the eye so it could heal. She was left with a slight clouding on the cornea. So much for the vaccination reducing the symptoms and her reaction. Fortunately, homeopathic remedies helped her heal quickly, much to the surprise of the veterinarian.

Risks of Routine Cat Vaccines

Acute Reactions Most Likely to Occur Within 24 Hours:

 1) Allergic reaction at site of injection (redness, swelling, itching)

 2) Lethargy

 3) Vomiting

 4) Diarrhea

 5) Fever

 6) Drooling

 7) Collapse

 8) Seizures

 9) Stiffness, soreness 

 10) Death, yes–death

These reactions are largely not reported, as there is no formal reporting procedure or requirement. Cat parents and vets don’t always associate the reactions with the vaccine. According to Dr. Ronald Schultz (a vaccine immunologist pioneer and expert for the University of Wisconsin, School of Veterinary Medicine), education on vaccine reactions is inadequate for veterinarians. I know a woman who took her two dogs in for their routine vaccines. The younger dog had no problems. The older dog had a severe reaction within a few hours–most of the symptoms listed above, except for the seizures and death. The veterinary office was closed, so she called her vet the next day. He was adamant that the vaccines he uses would not cause such a reaction. He would hear nothing of it. The reaction lasted two days, and her dog did pull through. It was so scary for her. I encouraged her to report the reaction to the vaccine company, but she would not pursue it, because the vet had shamed her.

Long-term problems strongly linked to routine vaccinations (a partial list):

1) Skin allergies

2) Autoimmune disorders such as Hyperthyroidism and Diabetes

3) Cancer

4) Arthritis and joint problems

5) Behavior changes

6) Injection site sarcomas (tumors), especially from the rabies vaccine–in fact, veterinary experts recommending injecting vaccines low on the back leg so it can be amputated if cancer develops, as opposed to injecting anywhere on the torso, where the cancerous tumors can more readily spread to organs. This right here tells us they KNOW vaccines can cause cancerous tumors. has very in-depth information, including a video relating to injection site tumors.

In 1978, Dr. Ronald Schultz  and his colleague, Dr. Fred Scott, published a vaccination protocol stating that after kitten vaccinations, a cat be vaccinated again in one year. After that, every three years or LESS frequently. There is growing evidence that the initial vaccinations last at least seven years and quite possibly a lifetime. Think measles: the measles vaccination lasts a lifetime.

It wasn’t until 20 years later that the American Association of Feline Practitioners (AAFP) announced guidelines similar to what he published 20 years before. I can’t help but wonder who was lining their pockets to take so long to finally admit it?

Things keep changing, the studies, the reports, the vaccines, the viruses mutating, etc. The latest guidelines from AAFP came out in 2013. They recommend to do the core (the 4-in-1) every three years, unless your cat is at high risk of being infected. But, please remember, vaccine immunologists have seen evidence for decades that the vaccines last at least seven years, if not a lifetime. If you care to read, here is the link. From there, click on “Download Feline Vaccination Guidelines” at the top.

So why do the majority of veterinarians still push annual vaccines and send us reminders? Any that I know do this. In 2016, I took a stray cat (Buddy) to a vet for FeLV testing and the FeLV vaccine. When I asked about the protection period, he told me in a very lowered voice,

“The FeLV vaccine probably lasts a lifetime. All the vaccines do. He probably does not need another one.”

And this veterinarian sends yearly vaccine reminders! His recommendation, though, being Buddy would continue to live outdoors (we tried to convert him to indoor living, but he sprayed and fussed A LOT) was to get just one more in a year to be on the safe side.

At the holistic practice I took Harmony to, the veterinary technician told us, also in a low voice, that all the core vaccines probably last at least three years, except for the FeLV, which should be done every year. So, they really don’t know either! 

Who Really Benefits from Routine Vaccines?

How much are veterinarians and pharmaceutical companies making?

Routine vaccinations are a HUGE portion of a veterinary clinic’s income. According to Dr. Andrew Jones, DVM, the mark-up is as much as 60%. According to Dr. Schultz,

there is absolutely no evidence that annual revaccination is necessary.

It is the pharmaceutical companies manufacturing the vaccines who state to repeat on the vaccine labels. Of course, why not, this brings in higher revenue dollars. The veterinarians follow it. And the more often you bring in kitty, the more money they make. Not to say that you should not take your cat in annually for a wellness exam to check for tumors, check the teeth and a cleaning, check the heart, etc. But they get cat lovers in by pushing the annual vaccines with those postcards or magazines with the cute little pictures, and trying to make you out to be a bad person if you don’t keep ’em up to date.

According to Karen Becker, DVM with Mercola Healthy Pets, the one-year and three-year rabies vaccines are identical. She also states that the same dose of vaccine protects a 350 lb tiger in the zoo as a 10 lb pet cat.

The Toxins in Vaccines

It’s not actually the vaccine material itself.  It is the ingredients and preservatives that build up in the cat’s organs and body and cause the problems over time.


Aluminum is the most commonly used adjuvant in killed-virus vaccines.  An adjuvant is a substance added to a killed-virus vaccine to enhance the immune system’s reaction (because the virus being used is killed and less effective at stimulating an immune system response–a killed-virus is less likely to replicate in the body).  Killed vaccines include Panleukopenia (FPV), Herpes 1 (FHV-1), Calicivirus (FCV), FeLV and Rabies.

No-kill or “live” vaccines (two versions known as Modified Live and Recombinant Live) are Rabies and FeLV. These can be in a live version because the virus is supposedly less likely to replicate in the host. So Rabies and FeLV vaccines can be either killed-virus or live vaccines.

It’s the adjuvant-containing vaccines that are most likely to cause vaccine-induced tumors. The tumor can be surgically removed, but in some cats grows back in multiples. It can lead to death. Aluminum has been found in removed vaccine-induced tumors.  Aluminum targets the brain and endocrine (hormonal) system. It builds up in the brain and nervous system causing degeneration, vaccine-associated cancers, seizures and behavior issues.

When I moved from California to Hawaii, the antiquated law in Hawaii required two sets of rabies vaccines within 90 days! It is no wonder the stories I heard of many pets never being the same, suddenly becoming ill, and dying after moving to Hawaii.  My pets had all kinds of problems when we lived in Hawaii, part of it due to the consistent warm wet weather, where viruses, mold, and fungi never die off. I am certain all the vaccines required to move there were also responsible. When I moved back to California from Hawaii, the rabies vaccination was required by California, even though Hawaii is rabies-free. (I know, it makes no sense!) I dreaded this, as they had already all received rabies vaccines. Two of my seven cats developed tumors within a few weeks at the site of the vaccine. Fortunately, homeopathy (again) came to the rescue. The tumors began dissolving within a few days, not to return.


Thimerosal is a mercury-based vaccine additive that’s used as a preservative. It’s not the only brand of preservative, and others also contain mercury.

In 1967, a study that was published in Applied Microbiology showed that Thimerosal killed mice when added to vaccines.

In 1972, Thimerosal manufacturer Eli Lilly found Thimerosal to be “toxic to tissue cells” in concentrations as low as one part per million (PPM)–100 times weaker than the amount used in a typical vaccine.

Veterinary vaccine manufacturer Pittman-Moore wrote to Eli Lilly: “We have obtained marked local reaction in about 50% of the dogs injected with serum containing dilutions of Merthiolate (Thimerosal). Merthiolate is unsatisfactory as a preservative for serum intended for use on dogs.” (Director of Biological Services, Pittman-Moore Company, letter to Dr Jamieson of Eli Lilly Company dated 1935. U.S. Congressional Record, May 21, 2003, E1018, page 9).

Since then, repeated studies show the dangers of Thimerosal.  

In 1982, the FDA proposed a ban on over-the-counter products containing Thimerosal.

In 1991 the FDA considered banning Thimerosal from animal vaccines. Considered? What or who stopped them from banning it?

In 2006, researchers at UC Davis published a study showing that Thimerosal may make the immune system vulnerable to bacteria and other pathogens.

Thimerosal-Free Vaccines?

In response to all the negativity surrounding Thimerosal, these were developed. But wait…. How about that little-known vaccine ingredient called an excipient. These ingredients are used in the production of vaccines, but aren’t an actual ingredient directly added to the vaccine. Thus, the manufacturer can claim the vaccine is Thimerosal-free, when it isn’t.

Save Your Money, Save Your Cat

So, please consider stopping the annual vaccinations, especially if your kitty has a reaction each time, is older, or is ill to begin with. Save your money for healthier food, dental gel, and some good supplements for better health and longevity. 

If you haven’t gotten my list of 10 ingredients in cat food to avoid, you can access it here: 10 Ingredients to Avoid.  This list identifies ingredients that are not supportive of a healthy immune system and constitution. Rather, these ten ingredients build up in the body and weaken it.  Choosing cat foods without these ingredients is very helpful in helping your cat detox from toxins and move toward thriving health.

If you’ve been getting annual vaccinations for your cat or any vaccines at all, please consider helping your cat detox as soon as possible! Learn how in the Healthy Cats Detox Workshop. Check it out here.

    From Sherry Daniel. My 3 cats are strictly indoor kitties. Yes, 2 of them have escaped, at different times, but weren’t around other cats. They are all fixed…that was only time they saw a vet. My female is almost 8 yrs old…never been sick. The other 2 are boys, 4 yrs old & never been sick. None have received ANY vaccinations.

      Hi Sherry, that is wonderful that your kitties have never been sick. Let’s hope they never are! Thank you for sharing your experience. What helped you decide to not vaccinate, other than them living indoors? Have you ever had cats that were vaccinated that did have a reaction to the vaccines?

    My 11-week-old kitten bit a vet after major surgery for pectus excavatum, and the City of Austin forced her into rabies quarantine (luckily at home), then forced me to vaccinate her for rabies at only 12 weeks….Help! How do I detox her?

      Hi Savannah, I’m sorry to hear about your kitten having to go through such a major surgery. She obviously associated the vet with the trauma she went through. You are a cat angel for making the decision to go forward with what I’m sure was a very expensive surgery. How is your kitten doing post surgery? Did or does she have any signs of reaction to the rabies vaccination? I truly believe there is no need to panic, so please try not to worry unless she is having a reaction. The problem with vaccines is mainly around repeated vaccination. If she has developed an injection site tumor, please do not hesitate to set up a complimentary Thriving Health Discovery Session with me at so we can determine if we can take care of this in one consultation or if you would like my full service offered in the Thrive Nutrition Program.
