UNSPSC 51201602: Brucella antigen

This classification denotes a vaccine against a genus of gram-negative, aerobic bacteria that causes brucellosis. Its cells are nonmotile coccobacilli and are animal parasites and pathogens. The bacterium is transmissible to humans through contact with infected dairy products or tissue.

UNSPSC 51201602 Brucella antigen is a Commodity code that in practice covers diagnostic and immunization antigens procured by state health departments. The recent state and local activity under this code reflects procurement of vaccines and related biological products for public health programs, though the most recently posted opportunity involves a different antigen than the code's nominal scope. State health departments are the primary issuing bodies soliciting under related codes in this family, pursuing sole source designations and competitive procurements for biologics and diagnostic materials needed to support disease prevention and control programs.

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 to sole source classification due August 3, 2026 at 10:00 a.m. CST. The notice does not specify quantity, contract term, estimated value, or pricing. Entities objecting to the sole source designation must submit written notice with detailed explanation and supporting documentation demonstrating alternative vendor availability to Cynthia Brasher at the Mississippi State Department of Health Purchasing Department. If substantiated objections are received showing the commodity is available from alternative sources, the department will withdraw the sole source publication and conduct an advertised competitive bid or selection process. Recent activity under the code shows limited geographic spread; the source material does not indicate procurement activity in other states or jurisdictions during the current period.
