CHP works on two fronts – gathering evidence and engaging the right stakeholders. An Immunization Tracking Tool was developed to collect real-time data on vaccine service delivery and budget absorption. This data is used to produce fact sheets and policy briefs for decision makers. A community documentary was also produced capturing the voices of facility champions, mothers, healthcare providers and county officials. On the stakeholder side CHP engages the County Governor, Members of County Assembly, Members of Parliament, Ministry of Health officials and county finance teams to build informed champions who advocate for increased immunization funding.
