Vital Wave partnered with a global alliance seeking to develop a five-year investment strategy to improve data use within immunization programs across low- and middle-income countries (LMICs). The firm designed a multi-day convening to gather inputs from expert stakeholders and country representatives to help shape the future strategy as well as immediate future investment priorities. Through a series of discussions, participants collaboratively identified horizon goals, specific strategic options, and immediate next steps. Key inputs included the identification of priority use cases for immunization data use, the current immunization funding landscape, and identification of gaps. The alliance used the results for their strategic planning as well as to further buy-in from other stakeholders and donors in the immunization data use space.
