The latest obligation on the International Reagent Resource contract, which began in 2019, funds CDC's provision of biological reagents and reference materials for global infectious disease research.

IRR supplies critical diagnostic and research materials to laboratories worldwide, enabling rapid response to emerging pathogens and pandemic preparedness—essential infrastructure for global health security.

This sustained funding ensures stable supply of standardized biological reference materials to academic, government, and commercial labs globally, reducing fragmentation in diagnostic development.

Control over reagent standards and reference materials is strategically important; U.S. leadership in IRR ensures American labs and allies access reliable, uncontaminated biological resources independent of foreign suppliers.
