Impact evaluation of immunisation service integration to nutrition programmes and paediatric outpatient departments of primary healthcare centres in Rumbek East and Rumbek Centre counties of South Sudan.

Integration of immunisation service delivery to nutrition sites and children's outpatient departments improved the immunisation coverage and decreased drop-out rates in the Rumbek East and Rumbek Centre counties of South Sudan. This evidence of positive impact should encourage the stakeholders of the Expanded Programme on Immunisation to focus on the sustainability and scale-up of this intervention to other counties in South Sudan, as logistically as possible.
