UNSPSC 51201822 Ancestim is a Commodity code covering specific pharmaceutical products, including vaccines. State and local health departments procure individual vaccine products under this code to fulfill immunization programs, disease prevention mandates, and public health requirements. The Mississippi State Department of Health's sole source notice for Yellow Fever Vaccine exemplifies the type of procurement activity: health agencies must often source particular vaccines by brand or manufacturer when clinical protocols, supply contracts, or sole availability requirements dictate a single-source purchase. Issuing bodies soliciting under this code are primarily state health departments and public health authorities; school districts and municipalities with public health functions may also participate in vaccine procurement, though state-level health agencies drive the majority of activity.

The most recent recorded opportunity is the Mississippi State Department of Health's sole source procurement notice (3150006922, due August 3, 2026) for Yellow Fever Vaccine from Sanofi Pasteur, Inc. The notice invites objections demonstrating alternative sources exist; if substantiated objections are received, the department will conduct a competitive bid process, otherwise it will appeal to the Public Procurement Review Board. The source provides no geographic spread beyond this single Mississippi opportunity and no visibility into activity in other states or regions under this code. No contract value, term, or quantity is specified in the notice.
