“Administration of rabies virus vaccines to cats is subject to inconsistent state and local statutes. In some cases, the requirements fail to consider the duration of protection such vaccines induce; annual administration of rabies vaccines approved for triennial administration is required in many locals. Veterinary organizations should continue to work with state and local governing bodies to ensure that rabies 4 virus vaccine regulations are consistent with the known duration of immunity of available vaccines.”
~ Richards J, 2000 Report of the American Association of Feline Practitioners and the Academy of Feline Medicine Advisory Panel on Feline Vaccines.

“Every effort should be made to change laws that require vaccination with this rabies product more often than every three years since annual vaccinations cannot be shown to increase efficacy and it is known to increase adverse events.”
