UNSPSC 51201625: Yellow fever vaccine

This classification denotes a vaccine that addresses an acute infectious disease primarily of the tropics, caused by a virus and transmitted to man by mosquitoes of the genera Aedes and Haemagogus. Yellow fever vaccine bears US NLM identifiers UMLS ID C0301508 and NCI Concept Code C96396.

UNSPSC 51201625 Yellow fever vaccine is a Commodity code covering immunization products procured by state and local health departments for disease prevention and public health programs. State and local governments acquire yellow fever vaccines to support vaccination clinics, travel medicine services, and disease surveillance activities. The Mississippi State Department of Health is the primary recent issuing body on record, pursuing vaccine supply through sole source procurement rather than competitive bidding, which signals either established supplier relationships or perceived single-source availability in the market.

The recent activity centers on the South region, specifically Mississippi, where the state health department posted a sole source notice on July 13, 2026, with an objection deadline of August 3, 2026, to procure yellow fever vaccine from Sanofi Pasteur, Inc. The procurement mechanism — a sole source designation with a formal objection window — differs from standard competitive RFPs or IFBs; parties may challenge the sole source classification by submitting written objections with evidence that alternative vendors can supply the vaccine. The notice does not disclose quantity, contract term, or estimated value. This code shows limited recent activity; the single posted opportunity suggests either infrequent procurement cycles for yellow fever vaccine or limited transparency in state and local health department purchasing for routine immunization supplies.
