Using Ipsos household data, latent class analysis, and gender-dynamics mapping, it identifies socio-cultural, cognitive, and informational barriers that limit vaccine uptake. A review of 58 global interventions informs a set of behaviourally grounded recommendations—spanning community-led communication, mHealth reminders, social-norm messaging, and improved health-worker interaction—to address demand-side frictions. The report offers a scalable framework for strengthening routine immunization in low-resource settings.Closing the Immunization Gap in Mozambique: A Behavioural Science Approach to Vaccine UptakeWorking Paper
