Kris Christine, Founder of the Rabies Challenge Fund with renowned vaccination expert Dr. Jean Dodds, is the person most responsible for changing rabies laws from one or two years to three in every state (but not every locale yet). Brava Kris! Her passion for this began when her beautiful dog Meadow died from an injection site fibrosarcoma after a rabies shot.
Here is an excerpt from a letter Kris recently sent trying to prevent a change in the law in Muncie, Indiana, from three years to one! This move is clearly to bring in more revenue with more frequent licensing, as the science in no way supports it.
This letter has valuable information we all should read — especially if you’re living in an area requiring shots more often than the national standard of every three years.
“… recommendations of the American Veterinary Medical Association  and the Center for Disease Control’s National Association of State Public Health Veterinarian’s 2008 Compendium of Animal Rabies Prevention and Control advise that: “Vaccines used in state and local rabies control programs should have at least a 3-year duration of immunity…….. No laboratory or epidemiologic data exist to support the annual or biennial administration of 3- or 4-year vaccines following the initial series.”
A regressive ordinance revision requiring annual rabies boosters for dogs and cats is medically unnecessary and scientifically unfounded. According to the American Animal Hospital Association, “The minimum DOI [duration of immunity] for killed rabies vaccine based on challenge studies is 3 years; based on antibody titers, it is considered to be up to 7 years..” 
More frequent vaccination than is required to fully immunize an animal will not achieve further disease protection. Redundant annual rabies shots needlessly expose dogs and cats to the risk of adverse effects while obligating residents to pay unnecessary veterinary medical fees, which could violate … consumer protection laws and obligate veterinarians to engage in unprofessional conduct (Code 25-1) by administering medically unwarranted rabies vaccines in order for their clients to comply with the amended ordinance. The American Veterinary Medical Association’s 2001 Principles of Vaccination state that “Unnecessary stimulation of the immune system does not result in enhanced disease resistance, and may increase the risk of adverse post-vaccination events.”
It is recognized that most, if not all, currently licensed annual rabies vaccines given annually are actually the 3-year vaccine relabeled for annual use — Read more »
