UNSPSC 51201604: Diphteria vaccine

This classification denotes a vaccine for a localized infection of mucous membranes or skin caused by toxigenic strains of corynebacterium diphtheriae. It is 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.

UNSPSC 51201604 Diphtheria vaccine is a Commodity code that classifies immunizations procured by state and local health departments. The sole recent opportunity in the source—a notice of proposed sole source procurement by the Mississippi State Department of Health—involves Yellow Fever Vaccine rather than diphtheria vaccine, indicating a mismatch between the code designation and the actual solicitation. State and local public health agencies use this code to acquire routine and emergency immunizations for disease prevention programs, epidemiological response, and population health initiatives. The procuring bodies are typically state departments of health and subordinate local health authorities, which manage vaccine inventories, distribution networks, and compliance with immunization schedules.

The source documents minimal recent activity under this code. The only posted opportunity is the Mississippi State Department of Health's proposed sole source procurement for Yellow Fever Vaccine from Sanofi Pasteur, Inc., posted July 13, 2026, with an objection deadline of August 3, 2026 at 10:00 a.m. CST. This is not a competitive solicitation but a notice inviting challenges to sole source classification; interested parties must demonstrate that alternative vendors can supply the vaccine. The notice does not specify quantity, contract value, or term. The mismatch between the code's nominal scope (diphtheria vaccine) and the actual solicitation (yellow fever vaccine) suggests either a tagging error or that this Commodity code covers a broader vaccine family than its name implies. Without additional recent opportunities, the geographic spread and volume of activity under this code cannot be reliably characterized from the source.
