New Hampshire rabies titer bill stalls after public health pushback

New Hampshire lawmakers considered House Bill 1488, a proposal that would have let some dogs, cats, and ferrets skip required rabies booster shots if a veterinarian supported an exemption based on antibody titer testing. The bill, sponsored by Rep. Keith Ammon, was framed as a response to pet parent concerns about vaccine adverse events and the cost of repeated boosters. But the proposal ran into opposition from veterinarians and public health officials, who argued that rabies titers aren’t an accepted substitute for vaccination under current national guidance. As of March 31, 2026, the measure did not become law and was sent to interim study. (citizenscount.org)

Why it matters: For veterinary professionals, the debate highlights a recurring tension between individualized patient care and population-level rabies control. National guidance from AAHA says rabies antibody titers are not considered a substitute for vaccination, and New Hampshire public health materials still tie exposure management to documented vaccination status, with much stricter quarantine or euthanasia pathways for unvaccinated animals. That means any move to recognize titers for routine legal exemptions could create confusion around compliance, liability, bite investigations, and post-exposure case management. (aaha.org)

What to watch: Watch whether New Hampshire’s interim study leads to a narrower medical-exemption framework, or whether similar titer-based exemption bills surface in other states. (citizenscount.org)
