Introduction

Immunization Information Systems (IIS) are critical public health tools that support immunization program business processes, vaccination coverage assessment, outbreak response, and data-driven decision-making to improve population health.¹

Jurisdictions receive regular funding for their IIS through their CDC Vaccine Preventable Disease Prevention and Response Cooperative Agreement. However, many IIS face sustainability challenges due to increased operational costs, funding challenges, workforce turnover, and costs associated with modernizing aging technology.² This toolkit provides a practical guide to help state, tribal, local, and territorial (STLT) health agencies strengthen and sustain their IIS through diversifying funding and controlling or reducing costs through optimizing efficiency.

The goals of the toolkit are to:

Define IIS sustainability and why it matters.
Highlight strategies and approaches to diversify funding and enhance IIS efficiency through leveraging Medicaid match, billing health plans for IIS data, increasing the use of shared services, leveraging shared infrastructure, adopting open source software, implementing process automation, and modernizing the IIS.
Offer tools and resources to support implementation of strategies and approaches for diversifying funding and optimizing IIS efficiency.
Provide practical “Success Stories from the Field” that illustrate how jurisdictions have successfully applied sustainability strategies and approaches and what others can learn from their experiences.
