An early version of the C4P-HPV tool was used for Gavi-supported demonstration projects on sub-national level costing. A version was then developed for national scale-up of HPV vaccination, which was successfully field tested in the United Republic of Tanzania and Rwanda and later refined following a workshop attended by representatives of five WHO regions in 2011. The refined tool was reviewed by the Immunization and Vaccine related Implementation Research Advisory Committee (IVIR-AC) in September 2012.

Major updates in both modules have been implemented in 2019 and a modified tool has also been field tested in the United Republic of Tanzania, Myanmar and Uzbekistan in this same year. The tool continues to be updated in response to feedback from WHO consultants and other users.

In addition to being available on its own, the C4P-HPV tool has also been incorporated into the OneHealth tool to allow consideration of HPV vaccine introduction in the context of other national health programmes.

The OneHealth tool is a single framework for all major diseases and health components that estimates the health inputs, resources and costs of national strategic health plans in low- and middle-income countries. The OneHealth tool is available from Avenir Health and more information is available from WHO-CHOICE.

The C4P tool produces cost estimates to aid decision making in HPV and cervical cancer prevention and control strategies. Although every effort has been taken to ensure that the cost estimate is representative of actual spending, the C4P estimate cannot be interpreted as the actual expenditure of the programme.
