"Are we ready to transition from the Global Alliance for Vaccines and Immunization support?" Perceptions from 15 Kenyan counties

Introduction: Gavi, the Vaccine Alliance, defined a transition roadmap for countries receiving funding support based on their income status projections. According to the latest projections, Kenya will complete their transition from vaccine funding in 2029. While eligible countries are kept informed and supported for a smooth transition process, the extent to which countries understand the significant implications of a complete end of GAVI support on immunization service delivery varies. Furthermore, whereas studies have been conducted to assess national preparedness for transition, there is a paucity of data on the understanding of subnational authorities of this process. In this study, we explored the perspectives of county-level stakeholders on Kenya's preparedness for GAVI transition. Methods: using purposive sampling, 77 senior county officials from 15 counties were selected for in-depth interviews. Data were collected using a semi-structured interview guide, transcribed, and thematically analysed. Ethical approval for the study was granted by Moi University Institutional Ethics and Research Committee. Results: findings reveal a consensus among respondents that both national and county governments are not fully prepared for the end of the Gavi Alliance. Concerns were highlighted around a lack of knowledge about vaccine costs, post-transition funding sources, and potential disruptions in immunization services. Respondents advocated for a phased transition, continued donor support, clear funding allocation, and legislative measures to ensure financial sustainability. Moreover, advocacy and awareness efforts, capacity building, and a robust legal framework were emphasized as essential for a smooth transition. Conclusion: Kenya's immunization bill, after the end of the financial support provided by Gavi Alliance is expected to be significant. This study underscores the importance of effectively engaging the subnational (county) level authorities. Successful transition from Gavi's support requires a strategy that promotes awareness and improves communication regarding the expected impact of the impending transition from Gavi on a sustainable immunization financing in Kenya.
