New Hampshire bill tests titer-based rabies exemptions

New Hampshire lawmakers considered a bill that would let some dogs, cats, and ferrets avoid future rabies boosters if a veterinarian issues an exemption based on antibody titer testing. House Bill 1488 would keep the initial rabies vaccine and the 9- to 12-month revaccination requirement, then allow annual exemptions for animals that meet the bill’s titer-testing standard. The proposal drew pushback from state veterinary officials and public health voices, who argued that rabies antibody levels aren’t an established substitute for vaccination. As of March 11, 2026, the bill was referred for interim study rather than advancing directly. (legiscan.com)

Why it matters: For veterinary professionals, the debate goes beyond booster intervals. It touches liability, exposure management, client communication, and the line between medical exemption and policy carveout. Current guidance from AAHA says rabies antibody titers are not an accepted correlate of protection and shouldn’t replace vaccination, while New Hampshire already has a medical exemption pathway for animals whose health would be endangered by vaccination. If states begin treating titers as a legal alternative, practices could face more pressure from pet parents seeking exemptions that conflict with prevailing rabies control standards. (aaha.org)

What to watch: Watch whether New Hampshire revives HB 1488 after interim study, and whether other states test similar titer-based rabies exemption proposals. (legiscan.com)
