Table 1. Key definitions.

Delivery experience	The specific target population (age range in years or school grade) and vaccination venue (health facility-based, school-based, outreach, or a combination of the three) within a specific project/programme (defined by the funding source). E.g. A country that was funded for 2 years for a demonstration project and implemented one year of school-based delivery and a second year of health facility based strategy, was classified as having contributed information from one project but two delivery experiences.
Programme	A national HPV vaccination programme.
Project	The activities funded through a specific GAP, Gavi or other funder support for a demonstration/pilot project. A distinct project was defined by the funder and/or implementer and grant award details.
