ThinkWell is pleased to present an updated version of the Immunization Delivery Cost Catalogue, or IDCC, the most comprehensive, current, and standardized database on the cost of delivering vaccines in low- and middle-income countries. Based on a systematic review of over 22,000 publications, the updated IDCC presents 1,156 unique unit costs from 119 publications, in 2022 US$. First developed in 2017 by ThinkWell under the Immunization Cost Action Network (ICAN) project, the IDCC was previously updated in 2018 and 2019. This update adds 607 unit cost from 62 studies—including from 12 countries previously not represented in the IDCC.
The IDCC comes with an analysis brief which summarizes the state of the evidence on immunization delivery cost, provides ranges for delivery cost per dose, and highlights remaining evidence gaps. Additional accompanying products include its Methodology note and the Codebook and Definitions document.
