UNSPSC 51204210: Equine/horse vaccine

The AAEP core vaccination list consists of rabies, Eastern and Western equine encephalomyelitis (EEE/WEE), tetanus, and West Nile virus (WNV).

UNSPSC 51204210 Equine/horse vaccine is a Commodity code that in practice captures immunization products for animal health, including equine vaccines and, based on recent state procurement activity, human vaccines procured through state health department channels. State and local governments acquire vaccines under this code through health departments and related public-health entities that manage immunization programs and disease prevention initiatives. The scope encompasses both routine animal health products and specialized vaccines for disease control, with issuing bodies primarily state health departments handling procurement for public-health missions.

Recent state-level activity shows limited volume under this code. The Mississippi State Department of Health posted a sole source notice on July 13, 2026 for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objections due August 3, 2026 — a procurement vehicle that permits challenge only if an alternative vendor can demonstrate equivalent supply capability. The notice does not disclose quantity, contract term, or estimated value, and the mismatch between the code's nominal scope (equine vaccines) and the actual solicitation (human immunization products) suggests either administrative miscoding or that the code serves as a catch-all for specialized vaccine procurement across animal and human health contexts. State and local procurement activity under this code remains sparse; business development professionals should monitor state health department notices for infrequent vaccine acquisitions, but should not expect regular or volume-driven opportunity flow under this classification.
