The availability of regular immunization expenditure data—generated by tools such as Health Accounts—provides immunization program managers with an evidence base for planning and ensuring adequate funding. The goal of this primer is to 1) describe methodologies for generating immunization spending data, 2) describe the types of policy and program issues the data can help address and 3) discuss how immunization program managers (and policymakers, where appropriate) can support the production and use of immunization expenditure data.

The Immunization Resource Tracking Project is supported through a grant from the Bill and Melinda Gates Foundation.
