UNSPSC 51201631: Diptheria and tetanus toxoids and acellular pertussis vaccine

This clasification denotes a compound preparation. The first component of this preparation addresses a localized infection of mucous membranes or skin caused by toxigenic strains of corynebacterium diphtheriae characterized by the presence of a pseudomembrane at the site of infection. diphtheria toxin, produced by C. diphtheriae, can cause myocarditis, polyneuritis, and other systemic toxic effects. The second component of this preparation addresses a disease caused by tetanospasmin, a powerful protein toxin produced by CLOSTRIDIUM TETANI.

UNSPSC 51201631 Diphtheria and tetanus toxoids and acellular pertussis vaccine is a Commodity code that state and local health departments use to procure vaccines and immunological products, though recent activity in this code shows limited specificity to the nominal product line. The source contains one recent opportunity posted by the Mississippi State Department of Health, but that solicitation seeks Yellow Fever Vaccine from a single source (Sanofi Pasteur, Inc.) rather than the diphtheria-tetanus-pertussis formulation the code nominally describes. State and local health departments, particularly state-level public health agencies, are the primary issuing bodies under this code family for vaccine procurement.

The recent activity comes from Mississippi, where the State Department of Health posted a sole source notice on July 13, 2026 with an objection deadline of August 3, 2026 at 10:00 a.m. CST. The notice invites written objections to the sole source designation, directed to Cynthia Brasher in the Purchasing Department at Cynthia.brasher@msdh.ms.gov, demonstrating alternative vendor availability. If objections are substantiated, the department will conduct a competitive bid; if the department upholds sole source status, it must appeal to the Public Procurement Review Board. The notice does not specify contract value, quantity, or term. The mismatch between the code's nominal scope and the Yellow Fever Vaccine purchase suggests either tagging error or broad classification of vaccine procurement under a single commodity code; state and local procurement activity under this code warrants verification against actual solicitation language before pursuing.
