UNSPSC 51201636: Lyme disease vaccine

This classification denotes vaccines for an infectious disease caused by a spirochete, borrelia burgdorferi, which is transmitted chiefly by Ixodes dammini and pacificus ticks in the United States and Ixodes ricinis in Europe. It is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. This disease was formerly known as Lyme arthritis and first discovered at Old Lyme, Connecticut.

UNSPSC 51201636 Lyme disease vaccine is a Commodity code nominally covering immunization products, but recent state and local procurement activity under this code shows little relevant buying. The single posted opportunity on record is a Mississippi State Department of Health sole-source notice for Yellow Fever Vaccine from Sanofi Pasteur, Inc., posted July 13, 2026, with an objection deadline of August 3, 2026. The opportunity is structured as a proposed sole-source procurement rather than a competitive solicitation, and the state is accepting written objections demonstrating alternative vendor availability; if substantiated objections are received, the department will initiate a competitive bid or selection process or appeal to the Public Procurement Review Board. The notice does not disclose quantity, contract term, estimated value, or pricing.

The code shows minimal recent activity and lacks a pattern of repeat solicitation or broad geographic spread. The single data point is a state health department procurement notice with no indication of parallel or follow-on opportunities across other jurisdictions or issuing bodies. Absence of activity at this code level does not signal no vaccination procurement across state and local government — vaccine buying occurs under related commodity codes and through cooperative purchasing vehicles — but practitioners monitoring 51201636 specifically should expect sporadic rather than steady opportunity flow.
