Lifelong Immunity – To Vaccinate or not

Lifelong Immunity – Why Vets Are Pushing Back
By Dogs Naturally Magazine in Bordetella, Vaccine Articles and News

The duration of immunity for Rabies vaccine, Canine distemper vaccine, Canine Parvovirus vaccine, Feline Panleukopenia vaccine, Feline Rhinotracheitis, feline Calicivirus, have all been demonstrated to be a minimum of 7 years by serology for rabies and challenge studies for all others.

In the Duration of Immunity to Canine Vaccines: What We Know and What We Don’t Know, Proceedings – Canine Infectious Diseases: From Clinics to Molecular Pathogenesis, Ithaca, NY, 1999, Dr. Ronald Schultz, a veterinary immunologist at the forefront of vaccine research and chair of the University of Wisconsin’s Department of Pathobiological Sciences, outlines the DOI for the following vaccines:
Minimum Duration of Immunity for Canine Vaccines:

Distemper- 7 years by challenge/15 years by serology
Parvovirus – 7 years by challenge/ 7 years by serology
Adenovirus – 7 years by challenge/ 9 years by serology
Canine rabies – 3 years by challenge/ 7 years by serology

Dr. Schultz concludes:  “Vaccines for diseases like distemper and canine parvovirus, once administered to adult animals, provide lifetime immunity.”  “Are we vaccinating too much?” JAVMA, No. 4, August 15, 1995, pg. 421.

Yet vets continue to vaccinate annually.  Dog owners feel that their vets are doing their dogs a great service by vaccinating every three years instead of annually – why do we allow it when these studies were done over thirty years ago and have been replicated time and again by other researchers?

Ian Tizard states:  “With modified live virus vaccines like canine parvovirus, canine distemper and feline panleukopenia, calicivirus, and rhinotracheitis the virus in the vaccine must replicate to stimulate the immune system. In a patient that has been previously immunized, antibodies from the previous vaccine will block the replication of the new vaccinal virus. Antibody titers are not significantly boosted. Memory cell populations are not expanded. The immune status of the patient is not enhanced.

After the second rabies vaccination, re-administration of rabies vaccine does not enhance the immune status of the patient at one or two year intervals.  We do not know the interval at which re-administration of vaccines will enhance the immunity of a significant percentage of the pet population, but it is certainly not at one or two year intervals. Tizard Ian, Yawei N, Use of serologic testing to assess immune status of companion animals, JAVMA, vol 213, No 1, July 1, 1998.

“The recommendation for annual re-vaccination is a practice that was officially started in 1978.”  says Dr. Schultz.  “This recommendation was made without any scientific validation of the need to booster immunity so frequently. In fact the presence of good humoral antibody levels blocks the anamnestic response to vaccine boosters just as maternal antibody blocks the response in some young animals.”

He adds:  “The patient receives no benefit and may be placed at serious risk when an unnecessary vaccine is given. Few or no scientific studies have demonstrated a need for cats or dogs to be revaccinated. Annual vaccination for diseases caused by CDV, CPV2, FPLP and FeLV has not been shown to provide a level of immunity any different from the immunity in an animal vaccinated and immunized at an early age and challenged years later. We have found that annual revaccination with the vaccines that provide long-term immunity provides no demonstrable benefit.”

Why then, have vets not embraced the concept of lifelong immunity in dogs?

“Profits are what vaccine critics believe is at the root of the profession’s resistance to update its protocols. Without the lure of vaccines, clients might be less inclined to make yearly veterinary visits. Vaccines add up to 14 percent of the average practice’s income, AAHA reports, and veterinarians stand to lose big.  I suspect some are ignoring my work,” says Schultz, who claims some distemper vaccines last as long as 15 years. “Tying vaccinations into the annual visit became prominent in the 1980s and a way of practicing in the 1990s. Now veterinarians don’t want to give it up.”

The report of the American Animal Hospital Association Canine Vaccine Taskforce in JAAHA (39 March/April 2003)3 includes the following information for vets:

   Misunderstanding, misinformation and the conservative nature of our profession have largely slowed adoption of protocols advocating decreased frequency of vaccination’; ‘Immunological memory provides durations of immunity for core infectious diseases that far exceed the traditional recommendations for annual vaccination.

‘This is supported by a growing body of veterinary information  as well-developed epidemiological vigilance in human medicine that indicates immunity induced by vaccination is extremely long lasting and, in most cases, lifelong.’

Both the AAHA and the AVMA must do more to “step up to the plate” says noted immunologist, Dr. Richard Ford. But the reality is the vets do not have to listen to the AAHA or the AVMA and it appears the state veterinary medical boards are not interested in enforcing vaccine schedules, opting to leave it up to the individual vet.

Dr. Bob Rogers hired a Chicago based law firm and initiated a class action suit for pet owners who were not given informed consent and full disclosure prior to vaccination administration. His article entitled “The Courage to Embrace the Truth”, states “While attending conferences like WSVMA and NAVMC I have asked over 400 DVMs from various parts of the country if they attended the seminars on New Vaccination Protocols. I was told by all but one, “I don’t care what the data says, I am not changing.” One DVM here on VIN even said “I am not changing until the AVMA makes me change.”

It seems that pet owners are against the wall when it comes to vaccination. The obvious conclusion is that pet owners who are concerned about the long term health of their companion animals must take it upon themselves to research vaccines, duration of immunity and vaccine dangers. At the very least, question every vaccine that goes into your animal – but none of the above information indicates you will get an honest or well-informed answer.

Be your dog’s advocate – protect him with knowledge and by taking a stand against unnecessary vaccination. His life may depend on it!

It's a touchy subject but it makes sense not to vaccinate yearly. We don't do it for humans so why dogs?
I understand that at least the dog gets a yearly checkup that it might not have gotten and I would definitely recommend keeping up with Rabies vaccines as it's not curable.

In the UK most vets are now recommending puppy vaccines, the first yearly booster and then the core vaccines every 3 years and a Lepto vaccine annually depending on the area you live/visit.

Dempsey has had his 2nd boosters (last year), and to be honest, I probably won't vaccinate him again. I do keep up with the Lepto jabs, though, because Northampton does have a high rat population and a lot of water courses so Leptospirosis is a problem.

You have to be sensible about it.

Yes, you do. I certainly wouldn't go back to annual jabs. But to be honest, I didn't even vaccinate my last dog annually! He was done a couple of times, and never from about the age of 7.

Rabies, as you say, must be kept up to date in countries where it's prevalent.

Well I don't vaccinate anyway so nothing new to me, but am pleased to see the UK is slowly moving from yearly jabs to 3+ yearly ones instead.

I didn't vaccinate my Dobies after the first two or three years. My reasoning was that, as Shisa says, humans don't get vaccinated every year (my last vaccination was 50 years ago).

But Kuchar gets vaccinated every year. Why? Several reasons:-

1/ As I get older I get more scared about things
2/ I realised that an unvaccinated animal (or human) is relying on the fact that other animals (or humans) are vaccinated and so are less likely to pass diseases on
3/ I joined the "Fit for Life" scheme at my vets which spreads the cost of monthly Advocate treatments (against all sorts of nasties) and quarterly treatments of that little bone shaped tablet against tapeworm (forget its name - I've been at a spa all day today and am blissed out!). And included in this scheme is a yearly booster and check up.
4/ A small river runs at the bottom of my garden, and through the fields where Kuchar is walked. (Rats)
5/ A dog sniffs another dog's poo (or worse upon occasion!  sick ), also wee-mails which are sometimes licked. We as humans don't do this so are less likely to contract infection through these media.
6/ I have noticed that (as far as I can tell, and Kuchar has only had two yearly boosters as yet) that each yearly vac is different, so I presume and trust that my vet is not over-vaccinating against a disease that only needs 3 year boosters (for example) but that something like Lepto is included.

But this is my decision and my choice; no-one is forced to vaccinate against their will (except if they want to put their dog in boarding kennels, and I can understand this proviso).

Lynda just a point on no.2 that you put - herd immunity is a myth, unvaccinated animals/people don't rely on those who are vaccinated, as with a lot of vaccines the person/animal sheds the vaccine and this is what causes some of the problems happy

Ella, I know from past discussions that you have strong views on this subject, as do I.

So I think that this is something we should agree to disagree on?

When I had rescue dogs and puppies on and off the property all the time I vaccinated yearly. I also went into some dodgy places so I thought rather safe than sorry as distemper and parvo can stick to your shoes and be brought onto your property.

We all have to do what we feel best for our babies.

A good healthy debate or conversation is a great thing guys.

I vaccinate every year religiously. Kennel cough appeared next door as they don't vaccinate. It was awful, the dog was coughing, wheezing & gasping for air for far too long.
I also can't go to doggie school here if they are not current with their yearly shots & I have proof from the vets.

That's a very good article & I actually saw it on fb. I'll still get Dempsey's Lepto jabs done, but I doubt that I'll have any further core vaccines.
