UNSPSC 51201600: Vaccines and antigens and toxoids

This classification denotes a) suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa, or rickettsiae), antigenic proteins derived from them, or synthetic constructs, administered for the prevention, amelioration, or treatment of infectious and other diseases; b) substances that are recognized by the immune system and induce an immune reaction; or c) preparations of pathogenic organisms or their derivatives made nontoxic and intended for active immunologic prophylaxis.

UNSPSC 51201600 Vaccines and antigens and toxoids is a Class code covering the procurement of vaccines, vaccine administration services, and related immunization products by state and local health authorities. State and local governments buying under this code source specific vaccines (such as yellow fever vaccine) from manufacturers and contract for the delivery of vaccination administration across multiple clinic settings—fixed mass-vaccination sites, pop-up clinics, long-term care facilities, and homebound patient visits. The primary issuing bodies are state health departments and state purchasing offices acting on behalf of health agencies; school districts and local health jurisdictions also procure vaccines for routine immunization programs, though recent opportunities in the dataset are dominated by state-level actors.

Recent activity centers on two distinct procurement approaches. The Mississippi State Department of Health posted a sole source notice (Solicitation 3150006922, due August 3, 2026) for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with an objection period allowing competing vendors to demonstrate alternative supply. The State of Rhode Island Division of Purchases issued a Master Price Agreement open-enrollment solicitation (MPA 613 OE Vaccine Administration Services, Solicitation OEV26006424, due June 2, 2026) inviting qualified vendors to provide vaccine administration services under four modular components: fixed-site mass vaccinations (500 administrations per week), pop-up clinics (10 per week), long-term care facility clinics (10 per week), and homebound vaccinations (50 per week). Rhode Island's MPA imposes a 0.33 percent contract administrative fee and requires MBE participation documentation. Geographic activity in the recent dataset is split between Mississippi and Rhode Island; issuing bodies are state health and purchasing departments rather than municipal or county jurisdictions.
