Introduction

The Big Catch-Up (BCU) initiative was implemented by the Ministry of Health of South Sudan, with support from WHO, UNICEF, Gavi, and immunization partners, to identify and vaccinate children who missed routine immunization services and restore population immunity following disruptions caused by the COVID-19 pandemic and other health system challenges. A Rapid Convenience Monitoring (RCM) survey conducted across 26 counties assessed vaccination uptake, caregiver awareness, accessibility of services, and barriers to vaccination among 2,354 children. The findings demonstrate substantial progress in reaching previously missed children and reducing immunity gaps, while highlighting persistent geographic inequities, documentation challenges, and barriers that require targeted action to ensure every child is protected.
