Frequently Asked Questions
Should we be worried about an increase in the number of rabid cats and dogs in our state as a result of changing the rabies vaccination interval to three years?
Over a period of 25 years, 32 states have migrated to a 3-year vaccination interval. Their experience has shown that a three-year interval is sufficient to prevent human rabies. Additionally, states which have changed to a three-year interval did not experience an increase in the number of rabid dogs and cats. No correlation exists between a state's required vaccination interval and its incidence of rabid dogs and cats.
