New Hampshire bill would allow rabies titer exemptions

New Hampshire lawmakers are considering House Bill 1488, a proposal that would let some dogs, cats, and ferrets skip state-required rabies boosters if a veterinarian documents antibody titer results showing the animal maintains an immune response from prior vaccination. The bill would keep the initial rabies shot and first-year booster schedule tied to the National Association of State Public Health Veterinarians’ compendium, but create a new annual exemption pathway based on serial titer testing rather than routine revaccination. As introduced, the measure would allow an exemption either through the state’s existing multi-signature medical waiver route or through a single veterinarian who performs baseline and post-vaccination titer testing and then confirms future titers remain at or above that animal’s post-vaccination baseline. Reporting on the proposal says the testing could cost pet parents roughly $300 to $500. (legiscan.com)

Why it matters: For veterinary professionals, the bill would put state law at odds with long-standing rabies guidance from the NASPHV and AAHA, both of which say rabies antibody titers do not directly correlate with protection and should not be used as a substitute for current vaccination. That creates practical questions around legal status after bites or exposures, clinic policies, boarding requirements, and how veterinarians would counsel pet parents who see a positive titer as equivalent to being currently vaccinated.

What to watch: The key next step is whether HB 1488 advances in the New Hampshire Legislature, and whether public health and veterinary groups push for amendments or oppose the titer-based exemption outright. (citizenscount.org)
