To address seasonally induced effectiveness bias, the intervention impact during the postintervention period (July–December) in 2019 was compared with the same preintervention period (July–December) in 2018. Pentavalent vaccine uptake for the three doses and drop-out rates before (July–December 2018) and after (July–December 2019) immunisation service integration into the nutrition programmes and paediatric outpatient departments of primary healthcare centres of Rumbek Centre and Rumbek East counties, respectively.
Standard normal distribution test (Z-test) was used to generate 95% CIs for immunisation coverage rate ratio.
*Immunisation coverage rate ratio is significant.
