UNSPSC 51201827 Levamisole hydrochloride is a Commodity code that in practice covers pharmaceutical products and vaccine procurement by state health departments. The recent solicitation activity under this code shows state agencies purchasing or procuring vaccines and related pharmaceutical supplies through sole source and competitive channels. The Mississippi State Department of Health represents the issuing-body type most active under this code — state-level health and public-health purchasing offices that source vaccines and pharmaceutical inputs for public-health programs and disease prevention initiatives.

The Mississippi State Department of Health posted a sole source procurement notice (3150006922, 1301-27-R-RFIN-00001) on July 13, 2026, for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objections due August 3, 2026 at 10:00 a.m. CST. The notice invited competing vendors to demonstrate availability of equivalent products; if substantiated objections were received, the state would withdraw the sole source designation and conduct a competitive bid process, or the department would appeal to the Public Procurement Review Board. The solicitation did not disclose quantity, contract term, estimated value, or pricing. Activity under this code appears limited to recent state-level health department procurement; the geographic spread in the source is confined to Mississippi.
