An evaluation of polio supplemental immunization activities in Kano, Katsina, and Zamfara States, Nigeria: lessons in progress.

Background. As 1 of 3 remaining poliovirus-endemic countries, Nigeria has become key to the global polio eradication effort. We evaluated supplemental immunization activities, including team performance, communications/mobilization activities, and vaccine acceptance, in 3 high-risk states. Methods.aEuro integral We used structured survey and observation instruments, document review, and stakeholder interviews. Results.aEuro integral Observations or surveys were conducted at 1697 households. Vaccine acceptance ranged from 87%-94%; among households rejecting polio vaccine, 38% of mothers sought measles vaccine for their children. Teams performed between 4%-42% of assigned tasks. Conclusions.aEuro integral Acceptance is high but teams have a critical role in surmounting residual vaccine resistance.
