One of the most important vaccine research studies in veterinary
medicine is underway at the University of Wisconsin School of
Veterinary Medicine in Madison. Dr. Ronald Schultz, a leading
authority on veterinary vaccines and Chair of the Department of
Pathobiological Sciences, has begun concurrent 5 and 7 year challenge
studies to determine the long-term duration of immunity of the canine
rabies vaccine, with the goal of extending the state-mandated
interval for boosters. These will be the first long-term challenge
studies on the canine rabies vaccine to be published in the United

Dr. Schultz comments that: “We are all very excited to start
this study that will hopefully demonstrate that rabies vaccines can
provide a minimum of 7 years of immunity.”

This research is being financed by The Rabies Challenge Fund, a
charitable trust founded by pet vaccine disclosure advocate Kris L.
Christine of Maine, who serves as Co-Trustee with world-renowned
veterinary research scientist and practicing clinician, Dr. W. Jean
Dodds of Hemopet in California. The Rabies Challenge Fund recently
met its goal of $177,000 to fund the studies’ first year budget with
contributions from dog owners, canine groups, trainers,
veterinarians, and small businesses. Annual budget goals of $150,000
for the studies must be met in the future.

Dr. Jean Dodds, DVM states: “This is the first time in my 43
years of involvement in veterinary issues that what started as a
grass-roots effort to change an outmoded regulation affecting animals
will be addressed scientifically by an acknowledged expert to benefit
all canines in the future.”

Scientific data published in 1992 by Michel Aubert and his
research team demonstrated that dogs were immune to a rabies ch
challenge 5 years after vaccination, while Dr. Schultz’s serological
studies documented antibody titer counts at levels known to confer
immunity to rabies 7 years post-vaccination. This data strongly
suggests that state laws requiring annual or triennial rabies
boosters for dogs are redundant. Because the rabies vaccine is the
most potent of the veterinary vaccines and associated with
significant adverse reactions, it should not be given more often than
is necessary to maintain immunity. Adverse reactions such autoimmune
diseases affecting the thyroid, joints, blood, eyes, skin, kidney,
liver, bowel and central nervous system; anaphylactic shock;
aggression; seizures; epilepsy; and fibrosarcomas at injection sites
are linked to rabies vaccinations.

Study co-trustee Kris Christine adds: “Because the USDA does not
require vaccine manufacturers to provide long-term duration of
immunity studies documenting maximum effectiveness when licensing
their products, concerned dog owners have contributed the money to
fund this research themselves. We want to ensure that rabies
immunization laws are based upon independent, long-term scientific
