UNSPSC 51201634: Haemophilus influenzae B with diptheria and tetanus and wholecell pertussis conjugated vaccine

This classification denotes a vaccine for a) a species of haemophilus found on the mucous membranes of humans and a variety of animals; b) A localized infection of mucous membranes or skin caused by toxigenic strains of corynebacterium diphtheriae; A disease caused by tetanospasmin, a powerful protein toxin produced by clostridium tetani; and d) A respiratory infection caused by bordetella pertussis.

UNSPSC 51201634 Haemophilus influenzae B with diptheria and tetanus and wholecell pertussis conjugated vaccine is a Commodity code covering pediatric combination immunizations procured by state health departments and other public health authorities. State and local agencies buy this vaccine to support routine childhood immunization programs, disease prevention initiatives, and public health emergency response. The vaccine combines protection against multiple pathogens in a single administration, making it a standard component of state immunization schedules. Issuing bodies soliciting under this code are primarily state departments of health managing statewide vaccination programs and pediatric health services.

The most recent activity appears limited. The Mississippi State Department of Health posted a sole source procurement notice on July 13, 2026 (solicitation 1301-27-R-RFIN-00001, objections due August 3, 2026) for Yellow Fever Vaccine from Sanofi Pasteur, Inc.—a notice unrelated to the code's nominal Haemophilus influenzae B conjugated vaccine scope. The source contains no recent competitive solicitations, response dates, or activity across multiple jurisdictions that would establish geographic spread or issuing-body patterns under this specific code. The available record does not support characterization of current market activity or opportunity volume for the Haemophilus influenzae B combination vaccine.
