UNSPSC 51201900: Multiple sclerosis MS agents

This classification denotes drugs to treat an autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system, multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system, and visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction.

UNSPSC 51201900 Multiple sclerosis MS agents is a Class code under which state and local health departments procure pharmaceutical products. The recent activity under this code shows a significant mismatch between the nominal scope and actual purchasing: the Mississippi State Department of Health posted a sole source notice for Yellow Fever Vaccine from Sanofi Pasteur, Inc., a viral immunization product unrelated to multiple sclerosis treatment. State health departments appear to use this code for a broader range of vaccines and immunobiologicals rather than MS-specific therapeutics. The issuing bodies soliciting under this code include state-level health agencies managing vaccination programs and pharmaceutical procurement.

The code shows limited recent competitive activity. The Mississippi State Department of Health's Yellow Fever Vaccine sole source notice (posted July 13, 2026, with objections due August 3, 2026) is the primary recent state or local opportunity under this UNSPSC classification. The notice does not specify quantity, contract term, estimated value, or pricing; objections to the sole source designation must include written evidence of alternative vendor capability and be submitted to Cynthia Brasher at the Mississippi State Department of Health Purchasing Department. If substantiated objections are received, the department would conduct an advertised competitive bid or selection process; if the department determines sole sourcing is justified, it would appeal to the Public Procurement Review Board. The narrow recent activity and the mismatch between the code's nominal scope (MS agents) and the actual pharmaceutical being solicited (yellow fever vaccine) suggest this code sees limited use in state and local procurement and may warrant verification of correct UNSPSC classification before pursuit.
