UNSPSC 51204207: Blackleg vaccine

For the active immunisation of cattle and sheep against disease associated with infections caused by Clostridium chauvoei (black leg).

UNSPSC 51204207 Blackleg vaccine is a Commodity code that state and local health departments use to procure vaccines for disease prevention, though recent activity in this code shows limited volume. The work consists of purchasing doses of blackleg vaccine (or related vaccine products) for public health programs, typically in small quantities for stockpiling or targeted animal or human health campaigns. State health departments are the primary issuing bodies under this code, acting as the procurement agents for their departments of health or animal health divisions. The scope is narrow and episodic — purchases occur when vaccination programs require replenishment or when disease surveillance triggers procurement needs.

Geographic activity in this code is sparse and scattered. The most recent opportunity on record is a sole source procurement notice from the Mississippi State Department of Health posted July 13, 2026, with an objection deadline of August 3, 2026; notably, that notice seeks Yellow Fever Vaccine from Sanofi Pasteur, Inc., not blackleg vaccine, indicating a potential code misclassification or that state health departments use this code broadly across vaccine procurement regardless of the specific vaccine type. The notice does not specify quantity, contract term, or estimated value. Sole source designations are common in vaccine procurement when a single manufacturer holds regulatory approval or supply exclusivity, so bidding opportunity under this code is likely to be limited; pursuit should focus on establishing vendor relationships with state health departments and monitoring objection periods rather than competing for published solicitations.
