Verified Immunity. Informed Choice.

Advocating for Rabies Titer Testing as a verified alternative to over-vaccination for medically fragile and protected animals.

The Science of Verified Immunity

Moving from “Calendar-Based” Guesswork to “Evidence-Based” Protection.

1. The 0.5 IU/mL Threshold: The Global Benchmark

A Rabies Virus Antibody Titer (RVNA) isn’t just a “pass/fail” test; it is a precise measurement of your pet’s ability to neutralize the virus.

  • The WHO Standard: The World Health Organization (WHO) and the CDC recognize 0.5 IU/mL as the definitive “adequate response” to vaccination.

  • International Travel: This is the exact same standard required by “Rabies-Free” countries (like Hawaii, Japan, and New Zealand) for entry. If this level of immunity is trusted to protect entire island nations, it is more than sufficient for a pet living in Summit County.

  • The Reality: Many pets maintain levels far above 0.5 IU/mL for many years beyond their last booster. Re-vaccinating an animal that is already at or above this level provides zero additional protection.
