It is misrepresentation, a deceptive trade practice, for a Veterinarian to recommend, charge for, or administer a vaccine, where there is no scientifically proven benefit to the patient, or that a reasonable client would not elect to purchase or have administered if given the information necessary to make an informed decision .
1. The duration of immunity for Rabies vaccine, Canine distemper vaccine, Canine Parvovirus vaccine, Feline Panleukopenia vaccine, Feline Rhinotracheitis, feline Calicivirus, have all been demonstrated to be a minimum of 7 years by serology for rabies and challenge studies for all others.

Minimum Duration of Immunity for Canine Vaccines:
Distemper- 7 years by challenge/15 years by serology
Parvovirus – 7 years by challenge/ 7 years by serology
Adenovirus – 7 years by challenge/ 9 years by serology
Canine rabies – 3 years by challenge/ 7 years by serology
