Experiences from polio supplementary immunization activities in Anambra State, Nigeria

Routine immunization coverage is low in some States in Nigeria and contributes to the transmission of wild poliovirus. Anambra State has been polio-free since 2004. However, the risk of importation of poliovirus from travelers and migrants is a public health concern due to the commercial nature of the State. This paper reported experiences and lessons from supplementary immunization activities (SIAs) conducted in the State that will be useful to other settings experiencing low uptake of routine immunization.
