Annual Dog Vaccination Dangers

Overview of the Dangers of Annual Dog Vaccinations

The very real dangers of over vaccinationFor years, we have been told to vaccinate our pets annually. 
We are told we must never miss a vaccine appointment or our pets could fall ill and die of the diseases covered by these vaccinations.

If I were to ask you how many times you have had a TB, Polio, Smallpox or MMR jabs. In most cases you would reply that you had only had them once, or in the case of MMR normally twice.

This is from the UK Government's vaccine protocols for humans:

“Live vaccines Live attenuated virus vaccines, such as MMR, usually promote a full, long-lasting antibody response after one or two doses.

Now full and long lasting sounds to me longer than a year?

The core vaccines for dogs and cats are live attenuated vaccines. Core vaccines show an excellent correlation between the presence of antibody and protective immunity to a disease and have a long DOI (Duration of Immunity). Core annual vaccinations have been a cash cow for many years, for both the vaccine companies and the Vets that dispense them.

I believe that this revenue is created under false and misleading science and it is seriously detrimental to the animal's health. As long ago as 2004 a group of vets issued a Health Warning that said. "The present practice of marketing vaccinations for companion animals may constitute fraud by misrepresentation, fraud by silence and theft by deception" 

They should have added "and a threat to the life and wellbeing of your pet". That was over 12 years ago and still I see some of my client's vaccination certificates stamped with annual core vaccines. Where is the science that says dogs and cats need vaccinations regularly? There is none. 

Vaccinating annually is against the BVAs guidelines (British Veterinary Association)  The biggest Vaccine supplier in the UK is Intervet.  It would normally be their vaccines used when you visit your Vet. Intervet clearly state and have done for some time. The main core vaccines should not be more than once every three to four years.

That is a fairly bold statement. It does not suggest that the Vets should decide for themselves when they should vaccinate. I will repeat. Should not be more than once every three to four years. The BVA (British Veterinary Association, whom I contacted, stated to me

"The duration of immunity (DOI) for each medicine or product is different and veterinary surgeons must keep up to date with this information."  In 2010 the Veterinary Medicines Directorate  (VMD) wrote a letter to the two major veterinary publications Veterinary Record and Veterinary Times, explaining that recent trends in data mean that the DOIs for a number of common vaccinations (canine distemper, parvovirus, and adenovirus) are now three to four years. This is information that veterinary surgeons will be aware of and will be following."

Therefore, the Vets that are administering annual core vaccinations are clearly not following their professional body or the vaccine company’s guidelines. What would happen if a GP did that?

Vaccines can cause major health problems in our PetsSo Why Should it Concern Us
Vaccinations are believed to over stimulate the immune system, causing it to malfunction. They are contraindicated for dogs with already suppressed immune systems.  Modified live Vaccine (MLVs) have the potential to revert to the virulent form of the disease. Also indicated are the following:

Autoimmune haemolytic anaemia
A dreadful disease that usually kills a dog within days. The progress of the disease closely resembles the last stages of AIDS. 
Scientists in America published a paper during 1997, saying that there is strong evidence to link this disease with ANY vaccine.

Dr. Denis W Macey was reported in an American veterinary paper as saying that up to 22,000 cats develop cancer at the site of vaccination every year in the USA. 
American cats are now being vaccinated in the tail or leg so that they can cut it off when it becomes cancerous.

Genetic defects 
Dr. Larry Glickman at Purdue University has found that routinely vaccinated dogs develop auto-antibodies to a wide range of their own biochemicals, including DNA. The significance of this study is immense. It means that vaccines cause genetic defects.

Thyroid disease
Can be caused by vaccines, and it then becomes an inheritable condition. Once a dog has underlying thyroid disease, he or she only needs a trigger - from a vaccine, an environmental pollutant, from stress, or from dietary inadequacies - to develop full-blown life-threatening autoimmune diseases.

Dr. Jean Dodds, one of the world's foremost experts in canine vaccine reactions, writes: "Recent vaccinations with single or combination modified live-virus (MLV) vaccines are increasingly recognised contributors to immune-mediated blood diseases, bone marrow failure, and organ dysfunction." ( Dr. Dodds lists leukaemia, thyroid disease, Addison's disease, diabetes, and lymphoma as diseases that can be triggered by vaccines.

It appears and is believed that parvovirus was originally created by vaccines. This disease didn't exist prior to the 1970s. In fact, scientists tell us it was created by vaccine manufacturers who cultured the distemper vaccine on cat kidneys that were infected with feline enteritis.  This cat-enteritis-diseased distemper vaccine was then injected into dogs, and parvovirus suddenly reared its ugly head around the world at the same time. A naturally occurring epidemic would spread slowly across continents. Parvovirus appeared with a big bang, in line with multi-national vaccine companies distribution policies.

There are numerous scientific studies linking arthritis with vaccination, this is especially the case with the distemper vaccine. Vaccine components have even been isolated in the bones of arthritis sufferers post vaccination.

There are many, many research papers showing a link between allergies and vaccines. Animals with a genetic predisposition to allergies ('people' from families with a history of irritable bowel syndrome/Crohns disease/enteritis, asthma, hay fever, eczema, attention deficit disorder, and so on), can become more allergic, or become highly sensitised, when you inject foreign proteins (serums and organ tissue contained in vaccines) into them. Flea bite allergy? Apparently, that' is the result of vaccines.

Titer Tests and my Protocol On Vaccinations
There is something called a Titer test is pronounced TIGHT er. Also called serology and antibody testing, is a simple blood test to ensure that a dog or cat has responded to vaccination with a specific “core” virus vaccine.  If those antibodies are there then there is no reason to re-vaccinate your pets. This is now acceptable to kennels and catteries as proof of immunity.

Kennels , Catteries, and Vaccinations
I have personally fought long and hard for local kennels and catteries to adhere to the latest scientific evidence on the dangers of over vaccinations. There is now guidance with regard what is required by kennels and catteries in relation to up to date vaccinations. see the link to Kennels and Catteries at the bottom of this article.

Kennels and Catteries may find themselves committing and offence in accordance with the Animal Welfare Act 2006. Some of the regulations may lead to placing boarding establishments in contravention of those acts. It is an offence under the Act to cause harm or suffering, which may  arise due to unnecessary over-vaccination as promoted in the MLCs.


If an animal is already immune to a viral disease, or a particular vaccine is associated with severe adverse reactions and under investigation with the European Medicines Control Agency, as is the case with MSD’s Lepto 4 vaccine, then an animal may be made to suffer as a result of enforced administration of that vaccine. point this out to the kennels and catteries who try and insist on yearly vacinnation certificates

My protocol is this: I vaccinate at 8 and 10.5 weeks of age  No more vaccinations until my dog reaches 7 years old.  Then I have a Titer test, if that shows the necessary antibodies, then I do not have any more tests or vaccinations. I have never had a dog die of any of the diseases covered in the core or none core vaccinations. I must point out that I am not a vet, however, i know a number of vets that do the same as me on their own dogs.

New vets are required to swear a solemn oath when they finish their degree “primum non nocere” "first do no harm” I am not certain all of them are following that creed. I have written an in-depth article for those that which to research much deeper into this problem and it can be found here. That also covers non-core vaccines such as Leptospirosis and dog flu. This is a disgrace on an International level yet it appears no newspapers or news agencies are interested in the systematic over vaccinating of our pets. Purely for the god of profit, not the pets best interest

In-Depth the Dangers of Over Vaccination of Cats and Dogs

Kennels and Catteries

 Regularly updated the last update was January 2016


I understand what you are saying and, believe me, I would much rather vaccinate every 3 - 4 years BUT my insurance company insist on a yearly booster to validate cover for my dogs. What can I do??

Doglistener's picture

If your insurance company insists on annual vaccinations then they are recommending against the vaccine companies that state it is dangerous to vaccinate annually the British Veterinary Association (BVA) and the Worlds Small Animals Veterinary Association (WSAVA). You can sue them if they insist and a medical condition arises because of their demands on recommending against professional advice and manufacturers guidelines and vaccination protocols.

Thank you so much for writing the truth about dog vaccinations. We had a puppy at eight weeks who had received his first set of vaccinations at six weeks old. In my opinion this is too early. He was ill the day after we got him home.
Eventually we found out he had autoimmune haemolytic anaemia. We managed to keep him going for another four weeks as he would improve a little after steroids but quickly deteriorate again. It was heart breaking! I really believe it was caused by vaccinating him too early.
That was a year ago and six months later we had another pup. This time we waited until he was twelve weeks old to give him his first vaccinations. We made sure he was well socialised with other vaccinated dogs and took him out to friends houses. We even carried him around the neighbourhood whilst walking our other dog!
Thanks again for such a great article. I researched a lot when our puppy was sick and it seems many vets are too scared , or greedy, to speak out about over vaccination.

The information in this article is correct to a certain degree but misses to highlight that a yearly vaccination of leptospirosis must be given as this does not last for 3 years. The veterinary profession know the guide lines and follow them. Titre testing is done for those that request it and out of the 15 I have helped do only 1 patient has come back as fully vaccinated against all core parts of the 3 yearly vaccinations. It is very miss leading to simply write and article telling people that all vets are over vaccinating and out for money when they are simply doing our jobs and following the guide lines set my manufacturers who have spent millions in research. As for the insurance aspect if your pet became ill and it was preventable with a simple vaccination then unfortunately they will not cover this. The reason there has been a decline in outbreaks of distemper or parvovirus is because we vaccinate and those who don't are getting by because the majority of pet owners do.

First of all I did not say that ALL vets were over-vaccinating. I wonder if you could tell me where the science that states core vaccines should be given every three years comes from?. It was a sop to the vaccine companies and the vets. Dogs immune systems are quite similar roi humans we do not require core vaccines every three years.

These vaccine create antibodies that are normally stable until the immune system breaks down or serious illness lessens their effect. Core vaccines show an excellent correlation between the presence of antibody and protective immunity to a disease, and have a long DOI (Duration of Immunity).

In 2002, a landmark report published by the American Veterinary Medical Association (AVMA) Council on Biologic and Therapeutic Agents (COBTA) stated in part, "...the practice of re-vaccinating animals annually is largely based on historic precedent supported by minimal scientific data; unnecessary stimulation of the immune system does not result in enhanced disease resistance and may expose animals to unnecessary risks...". - See more at: https://www.doglistener.co.uk/depth-annual-dog-vaccination-dangers#sthas...

My concern is the Vets that are STILL core vaccinating annually. There is a large chain of vets quite well known that often does this. This leads me onto leptospirosis. I wonder if you could tell me how many cases of lepto did we have in the UK last year?. I am still trying to find out, however in previous years it has been as low as 45 out of approximately 8 million dogs.

I am sure you are aware that the vaccine does not cover all types of the strain found in the UK. Are you also aware that a proportion of the dogs HAD been vaccinated for Lepto and still caught it.

Eminent scientists in both the UK and America have called for the withdrawal of this vaccine, because it is ineffective to most of the strains of this disease. I that why every single dog with lepto in CHC's survey, contracted it within three months of being vaccinated.

One of the leading professors of immunology is Dr RD Shultz, professor and chair of the Department of Pathobiological Sciences, School of Veterinary Medicine, University of Wisconsin. His expertise is in Immunopathogenesis of viral diseases; developmental aspects of immunity; effects of environmental factors on immune systems; Studies are ongoing on development and/or testing of various adjuvants and vaccines for numerous bacterial and viral diseases of domesticated species. Basically I am saying that he really knows what he is talking about.

He has written many papers regarding vaccinations and immune-mediated medical problems and is one of the most well respected experts in his field. He states that he never vaccinates his own dogs for leptospirosis, even though he lives in a high risk area."

According to his survey on vaccination programs, "Approximately 30% of veterinary practices do not vaccinate for leptospirosis. The responding practitioners either didn't believe that leptospirosis was a significant problem in their area or the vaccine containing L. canicola and L. icterohaemorrhagiae serovars failed to provide protection."

I found this research interesting from Dr. Arnold Plotnick, D.V.M. (8) "Leptospirosis is a zoonotic (potentially contagious to humans) disease that affects the kidneys and sometimes the liver. It is caused by the bacterium Leptospira interrogans. The core vaccine that contains distemper, adenovirus, parainfluenza and parvovirus is also available with the leptospirosis organism".

"However, the Leptospirosis portion of the vaccine is the most reactive fraction of the combination core vaccine, and is a common offender in causing adverse vaccination reactions in dogs. In addition, the immunity conferred by the leptospirosis portion is believed to be short-lived, probably six months or less. For these reasons, we do not recommend the leptospirosis vaccine be routinely administered to all dogs."

I wonder if you could tell me how many cases in the last 5 years you have treated for Leptospirosis if any? How many had been vaccinated yet still contracted this disease? Please remember the CHC's (Canine Health Concern) findings in one calender year found that every single dog that contracted leptospirosis contracted it within three months of being vaccinated against it.

Given that this vaccination is the most reactive fraction of the combination core vaccine, and is a common offender in causing adverse vaccination reactions in dogs perhaps we should read more about this rare disease especially given the aggressive nature of this vaccine.

I rehomed a 7 month old Shih Tzu
The previous owner said he had been vaccinated, however she has not produced papers, she says she has lost them due to relationship breakup and having to move out. She has not supplied the name of vet. I rang all vets in locality and they have no record. My vet advised to repeat vaccinations as said that is the usual action if they have no record. He was quite sick after the first vaccine. Other than that he seems okay. I would welcome your comment please.

I would have chased up the owner and demanded details of vaccinations or at least the name of the vet. II shudder when i hear that young and old dogs have been revaccinated because they cannot find the papers.

Having had a puppy collapse and then die after her puppy vaccs, personally I think one vaccination is too many. I don't do any puppy vaccs now, I have 6 dogs, oddly, considering we are told how dangerous these disease are, and that our dogs will get them and then die, I have not had one single illness with any of mine!! It isn't like they are kept in an airtight bubble either. They used to go to dog shows, they walk in the local parks and pet shops, they go on holiday (in the UK) with us, they go walking in fields, in woodland and swim in any water they can find... They are all 100% healthy. I find it appalling that vets want to keep sticking these dangerous chemicals into innocent animals year in year out.

I think you are on the right lines. Try colloidal silver fpr anything viral.

I don to disagree that for most viruses, the vaccination schedule should not be annual. Most veterinary bodies and the RVC advise this. If someone goes to a vet who insists on yearly vacs, they should change vets and tell them the reason why. However I do take issue with several other points. Your comments on leptospirosis for example. Simply saying "how many cases do you hear of?" Implying that if there aren't any cases, the disease doesn't exist is flawed. It's the equivalent of saying measles isn't a problem because not many children get it. Maybe the disease does not cause more harm because the majority of dogs are vaccinated against it. Also, the standard vac now covers the 4 key antigens from the most prevalent strains, not 2. Of course there are cases of vaccinated dogs getting lepto because there is no vaccine, human or animal which is claimed to be 100% effective. Parvovirus was not man made, it is as a result of cross species transmission. Parvo has been known and identified in many carnivore species for much longer than the claimed 1970s you state. FPV since at least the 50s and in wild animal populations for much longer. Finally, you would gain much more respect and potentially a wider audience if you were balanced in your information. I refer to the list of side effects. If you really want to convince an audience, cite your scientific sources, not just "this important person said", I mean peer reviewed scientific studies into each of the side effects of vaccinating you claim. I agree with one of them as having sound scientific evidence and that is the injection sites in cats leading to tumours. Until someone shows me real evidence the rest smacks of scaremongering and I don't believe that is your intention
