UNSPSC 51201822 Ancestim is a Commodity code under which state and local governments procure pharmaceutical products, specifically biologics and vaccines for disease prevention. The Mississippi State Department of Health posted a sole source procurement notice on July 13, 2026, for Yellow Fever Vaccine from Sanofi Pasteur, Inc., signaling that at least some state health agencies classify vaccine procurement under this code. The scope covers the acquisition of immunological agents and related biologics through both competitive and sole source pathways; in the Mississippi case, the Department of Health asserted that Yellow Fever Vaccine is available exclusively from a single vendor, triggering a notice-and-objection process rather than a standard competitive bid.

The issuing body in the recent record is a state health department. The Mississippi State Department of Health notice shows a response deadline of August 3, 2026 at 10:00 a.m. CST for objections to sole source designation; if substantiated objections are received demonstrating alternative suppliers, the Department will conduct an advertised competitive bid or selection process, or will appeal the sole source determination to the Public Procurement Review Board. The notice does not specify contract quantity, term, estimated value, or pricing, limiting visibility into the scale of procurement activity under this code. The geographic focus visible in the recent-opportunities block is limited to Mississippi; the sparse record suggests this code sees minimal state and local procurement activity, or that most vaccine procurements are tagged to broader family- or class-level codes rather than this specific Commodity designation.
