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 covering animal health immunization products. State and local governments procure vaccines under this code for disease prevention and herd health management in equine and other livestock populations. The Mississippi State Department of Health represents the visible recent procuring body, though the scope and frequency of state and local vaccine procurement across other jurisdictions remain unclear from available opportunity records.

The most recent activity involves a sole source procurement notice posted by the Mississippi State Department of Health on July 13, 2026, for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objection deadline August 3, 2026. The notice does not specify quantity, contract term, estimated value, or pricing. The procurement is a proposed sole source purchase rather than a standard competitive solicitation; any entity may submit written objection demonstrating alternative vendor availability to Cynthia Brasher at the Mississippi State Department of Health Purchasing Department (Cynthia.brasher@msdh.ms.gov). If substantiated objections are received, the department will conduct a competitive bidding process or withdraw the sole source designation and appeal to the Public Procurement Review Board, which requires the department to bear the burden of proof that the vaccine is available exclusively from the sole source vendor.
