The Big Catch-Up (BCU) initiative was launched to support countries in identifying and vaccinating children who missed routine immunization during the COVID-19 pandemic. To better understand implementation experiences and operational lessons, several countries conducted case studies examining different aspects of BCU implementation. UNICEF, in collaboration with Gavi, WHO and partners, hosted a webinar to share insights from three selected case studies and reflect on lessons from programme implementation.

The session included:
• Country presentations highlighting experiences implementing BCU activities (Ethiopia, Kyrgyzstan, Mozambique)
• Reflections on operational approaches used to reach zero-dose and under-immunized children
• Discussion of lessons related to programme coordination, service delivery adaptations, and digital health systems
• Interactive Q&A and discussion

By the end of the session, participants had:
✔ Gained an understanding of how countries implemented BCU activities in different operational contexts
✔ Learned practical approaches used to identify and reach missed children
✔ Explored lessons related to programme coordination, service delivery, and monitoring systems
✔ Reflected on implications for strengthening routine immunization recovery efforts
