UK Vets Unite Against Over-Vaccination!

"The American Veterinary Medical Association Committee report that 'one year revaccination recommendation frequently found vaccination labels is based on historical precedent, not scientific data. There is evidence that some vaccines provide immunity beyond one year. According to research there is no proof that many of the yearly vaccinations are necessary and that protection in many instances may be life long'; also, 'Vaccination is a potent medical procedure with both benefits and risks for the patient'; further that, 'Revaccination of patients with sufficient immunity does not add measurably to their disease resistance, and may increase their risk of adverse post-vaccination events.' Finally, he states that: 'Adverse events may be associated with the antigen, adjuvant, carrier, preservative or combination thereof. Possible adverse events include failure to immunise, anaphylaxis, immunosuppression, autoimmune disorders, transient infections and/or long-term infected carrier states.'
Further, the evidence shows that the duration of immunity for rabies vaccine, canine distemper vaccine, canine parvovirus vaccine, feline panleukopaenia vaccine, feline rhinotracheitis and feline calicivurus have all been demonstrated to be a minimum of seven years, by serology for rabies and challenge studies for all others.

We, however, fully support the recommendations and guidelines of the American Animal Hospitals Association Taskforce, to reduce vaccine protocols for dogs and cats such that booster vaccinations are only given every three years, and only for core vaccines unless otherwise scientifically justified.

We further suggest that the evidence currently available will soon lead to the following facts being accepted:

* The immune systems of dogs and cats mature fully at six months and any modified live virus (MLV) vaccine given after that age produces immunity that is good for the life of that pet.
* If another MLV vaccine is given a year later, the antibodies from the first vaccine neutralise the antigens from the subsequent so there is little or no effect; the pet is not 'boosted', nor are more memory cells induced.
* Not only are annual boosters for canine parvovirus and distemper unnecessary, they subject the pet to potential risks of allergic reactions and immune-mediated haemolytic anaemia.

* Puppies and kittens receive antibodies through their mothers' milk. This natural protection can last eight to 14 weeks.

* Puppies and kittens should NOT be vaccinated at less than eight weeks. Maternal immunity will neutralise the vaccine and little protection will be produced.
* Vaccination at six weeks will, however, DELAY the timing of the first effective vaccine.
* Vaccines given two weeks apart SUPPRESS rather than stimulate the immune system.

This would give possible new guidelines as follows:

1. A series of vaccinations is given starting at eight weeks of age (or preferably later) and given three to four weeks apart, up to 16 weeks of age.

2. One further booster is given sometime after six months of age and will then provide life-long immunity.

In light of data now available showing the needless use and potential harm of annual vaccination, we call on our profession to cease the policy of annual vaccination.

It is accepted that the annual examination of a pet is advisable. We undervalue ourselves, however, if we hang this essential service on the back of vaccination and will ultimately suffer the consequences. Do we need to wait until we see actions against vets, such as those launched in the state of Texas by Dr Robert Rogers? He asserts that the present practice of marketing vaccinations for companion animals constitutes fraud by misrepresentation, fraud by silence and theft by deception.

The oath we take as newly-qualified veterinary surgeons is 'to help, or at least do no harm'. It is therefore our contention that those who continue to give annual vaccinations in the light of new evidence may well be acting contrary to the welfare of the animals committed to their care.

Yours faithfully,
