WHO convened a Vaccine Delivery Costing Working Group with experts from eight organizations working in immunization costing to address a lack of standardization and gaps in definitions and methodological guidance through developing a Consensus Statement harmonizing terminology and principles, and formulating recommendations for vaccine delivery costing for decision making.
The Working Group identified groups working in vaccine delivery costing and reviewed existing guidance documents and costing tools, focusing on those for low- and middle-income country settings. Four major workstreams on vaccine delivery costing as well as nine guidance documents and eleven costing tools for immunization costing were identified. Some terms and principles were found to be commonly defined while others were specific to individual workstreams.
This paper discusses the process, findings of the review, and recommendations for harmonizing differences in terminology and principles in the Consensus Statement.
Any organization or individual working in the field of immunization economics can submit findings, opportunities, calls to action, or other relevant work below to be shared with our community.
