Efter att forskningsresultat från WSAVA (World Small Animal Veterinary Association) har visat att det endast är nödvändigt att vaccinera hunden 2-3 gånger under hundens livstid, mot de tre allvarliga sjukdomarna, valpsjuka, hepatit (smittsam leverinflammation) och parvovirus (hundpest) vill de Danska veterinärförbundet ändra sina rekommendationer då de gäller vaccinering mot dessa tre sjukdomar.

De kommer att framöver rekommendera vaccination endast 2-3 gånger under hundens hela livstid.

Forskningen från WSAVA visar att 98% av alla hundar som vaccinerats en gång som valp och en gång då den nått ett års ålder, är beskyddade mot sjukdomarna resten av livet. Karin Ryborg från Danska veterinärförbundet säger till tidningen Lille hund att de haft en dialog med forskarna bakom resultatet och att de är överbevisade över att det räcker med att vaccinera sin hund två gånger i livet. Därför kommer veterinärförbundet i Danmark att rekommendera att deras medlemmar följer de nya direktiven.

Tidigare har veterinärerna rekommenderat att hunden skall vaccineras minst vart tredje år, men en del veterinärer har vaccinerat varje år för att vara på den säkra sidan. Vi har följt anvisningarna som kommit från tillverkarna av vaccinet och handlat i god tro säger Karin Ryborg. De nya direktiven gäller bara de tre kärnsjukdomarna valpsjuka, hepatit (smittsam leverinflammation) och parvovirus (hundpest).

Ju mer jag lär om hundars hälsa, desto mer övertygad blir jag om att vi (trots många varningar) fortsätter att vaccinera våra hundar alldeles för mycket.

För de som läser engelska utan större problem har jag här kopierat en artikel som publicerades i den brittiska tidskriften Veterinarian Times i januari 2004. Den beskriver många aspekter av det här problemet.

Det har hela tiden kommit fram mer forskning som visar på problem med frekventa vaccinationer. Själv kommer jag i framtiden så långt det är möjligt att följa de rekommendationer som ges i slutet av den här artikeln (röd markering). Om detta betyder att jag inte får delta på utställningar så gör jag hellre den uppoffringen än att jag gör mina hundar sjuka. För utställning gäller just nu att det ska vara högst tre år sedan sista vaccination i Norge, på hundar som är över ett år gamla, men fyra år i Sverige. Allteftersom kunskapen växer och sprids kommer säkert regler att ändras.

Dear Editor

We, the undersigned, would like to bring to your attention our concerns in the light of recent new evidence regarding vaccination protocol.

The American Veterinary Medical Association Committee report this year states that 'the one year revaccination recommendation frequently found on many vaccination labels is based on historical precedent, not scientific data'.

In JAVMA in 1995, Smith notes that 'there is evidence that some vaccines provide immunity beyond one year. In fact, 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.'

The report of the American Animal Hospital Association Canine Vaccine Taskforce in JAAHA (39 March/April 2003) is also interesting reading: 'Current knowledgte supports the statement that no vaccine is always safe, no vaccine is always protective and no vaccine is always indicated'; '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 as well-developed epidemiological vigilance in human medicine that indicates immunity induced by vaccination is extremely long lasting and, in most cases, lifelong.'

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.

The veterinary surgeons below fully accept that no single achievement has had greater impact on the lives and well-being of our patients, our clients and our ability to prevent infectious diseases than the developments in annual vaccines. 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.

* There is no scientific documentation to back up label claims for annual administration of MLV vaccines.

* 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.

Can we wonder that clients are losing faith in vaccination and researching the issue themselves? We think they are right to do so. Politics, tradition or the economic well-being of veterinary surgeons and pharmaceutical companies should not be a factor in making medical decisions.

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'. We wish to maintain our position within society, and be deserving of the trust placed in us as a profession. 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
