In 1978, when vets were vaccinating annually, Schultz et al published ‘‘An Ideal (But Not Proven) Immunization Schedule for Dogs and Cats’’. They recommended a series of puppy/kitten vaccinations followed by revaccination at 1 year, then revaccination every 3 years.
Research was initiated at that time to prove his suspicions and dogs where challenged with exposure to Distemper, Adenovirus and Parvovirus, anywhere from 1 to 11 years after vaccination. Every single dog was protected when exposed to the virus. “The results from this limited group of dogs clearly demonstrated the Norden modified live vaccines provided immunity for at least 11 years against CDV and CPV-2″ says Dr. Schultz. Based on this research, Drs Schultz and Scott recommended triennial revaccination instead of annual revaccination.
These early recommendations prompted the AAHA to assemble a task force. In 2003, the American Animal Hospital Association Canine Vaccine Task Force evaluated the data from these challenge and serological studies and, while noting that the core vaccines had a minimum duration of immunity of at least seven years, compromised in 2003 with the statement that “revaccination every 3 years is considered protective.”
Task force member Dr. Richard Ford, Professor of Medicine, North Carolina State University, said that the decision to recommend a 3 year revaccination schedule for core vaccines was a compromise. “It’s completely arbitrary…,” he said. “I will say there is no science behind the three-year recommendation…”
Today, eight years later, despite more and more research showing long lasting immunity for core vaccines and the deleterious effects of vaccination, the AAHA hasn’t changed it’s position all that much. The 2011 revaccination guidelines state: “every 3 years or more” with the following comment: “Among healthy dogs, all commercially available [core] vaccines are expected to induce a sustained protective immune response lasting at least 5 yr. thereafter”
Why do they state that the immune response lasts at least 5 years (and even this is a serious underestimation) yet stick to that magically arbitrary schedule of 3 years?
“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.
This is extremely problematic because, as the vets themselves have revealed, they are not prepared to make a decision on how often they should vaccinate and what vaccines they should give. In the end, the vets are over-vaccinating either out of ignorance or greed, and the governing bodies only seem interest in protecting the financial interests of their veterinary members. Speaking of that, it is noteworthy that the major sponsors of the AAHA guidelines are the major pharmaceutical companies that manufacture these vaccines.
