UNSPSC 51201639: Staphylococcus vaccine

This classification denotes a vaccine against staphylococcus aureus, an opportunistic bacterial pathogen, a genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters.

UNSPSC 51201639 Staphylococcus vaccine is a Commodity code under which state and local health departments procure vaccines. The recent solicitation activity under this code does not align with the nominal scope — the Mississippi State Department of Health posted a sole source notice in July 2026 for Yellow Fever Vaccine, not Staphylococcus vaccine, suggesting either a tagging misalignment or a broader vaccine-procurement category in practice. The solicitation represents the kind of work typically bought under this code: direct procurement of immunization products by state health agencies, often through sole source or limited-source arrangements when supply chains are constrained or vendor exclusivity agreements apply.

The recent activity shows minimal geographic spread and issuing-body diversity in the source record. The Mississippi State Department of Health is the sole identified issuing body. The Yellow Fever Vaccine procurement posted July 13, 2026 with an objection deadline of August 3, 2026 at 10:00 a.m. CST was structured as a sole source notice rather than a competitive RFP, RFQ, or IFB — objecting parties must demonstrate alternative sources to trigger competitive bidding. The notice does not disclose quantity, contract term, or estimated value, limiting visibility into procurement scale. Given the mismatch between the code name (Staphylococcus vaccine) and the actual solicitation (Yellow Fever vaccine), this code warrants clarification on whether it is actively used for staphylococcus immunization products in state and local practice or whether vaccine procurement more broadly is consolidated under a different UNSPSC classification.
