UNSPSC 51201605 Encephalitis virus vaccine is a Commodity code under which state health departments procure viral immunizations. The recent solicitation activity under this code involves procurement of encephalitis and related arboviral vaccines for public health distribution and immunization programs. The Mississippi State Department of Health is the principal issuing body in the recent record, pursuing a sole source procurement after determining that only one vendor meets the supply requirements for the specific vaccine formulation needed.

The Mississippi State Department of Health posted a sole source notice on July 13, 2026, for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with an objection deadline of August 3, 2026. The notice invites written objections with supporting documentation demonstrating that alternative vendors can supply the vaccine; if substantiated objections are received, the department will conduct a competitive bid process. The solicitation does not disclose quantity, contract term, or estimated value. Mississippi represents the only recent state or local activity visible under this code; geographic spread and issuing-body concentration cannot be characterized from the current record. The sole source structure and the specific vaccine formulation suggest that procurement under this code may be driven by public health requirements, supply constraints, or regulatory approvals rather than broad competition across multiple vendors.
