❇️ We are pleased to share this global Big Catch-Up (BCU) report which synthesizes lessons from five country case studies: Cameroon, Nigeria, Pakistan, the United Republic of Tanzania, and Yemen; focusing on how countries planned, implemented, monitored, and began institutionalizing catch-up immunization activities to reach zero-dose and under-immunized children.
EVIHDAF was proud to lead the Cameroon case study, documenting how BCU immunization activities were implemented across diverse settings, including urban, rural, remote island, and conflict-affected communities.
Along with this Global report, please feel free to dive deep into the Cameroon BCU case study report and evidence briefs here ➡️https://www.evihdaf.com/projects-reports/.
Together, these products offer practical lessons for strengthening immunization systems, closing immunity gaps, and ensuring that no child is left behind.
