In Nigeria, the Learning Hub has used knowledge translation to strengthen immunization financing through data-driven advocacy and stakeholder collaboration. By developing and applying the Immunization Accountability Framework, the Learning Hub supported government and civil society actors to track budgets, improve fund disbursement, and enhance transparency across multiple states. These efforts led to concrete outcomes—including full budget releases in Bauchi and additional funds secured in Kano and Sokoto—demonstrating how financial data and local engagement can drive real change. The Spotlight highlights how knowledge translation strategies are unlocking resources to reach more zero-dose children.
