Background
Immunization is a known cost- effective public health intervention that saves millions of lives every year [One of the pro-equity strategies is a focus on disaggregation of sub-national data which is able to highlight inequitable access and poor utilization of immunization services [Ensuring a system of obtaining reliable immunization data remains a challenge. Some of the cited data challenges include an unstable denominator and a transient population [Over the last decade, there has been a growing interest in introduction and re-vitalization of national CHW programs in low-and middle-income countries [In Uganda, CHWs are drawn from and expected to work in their communities [There are few studies that have quantitatively assessed role of CHWs in immunization [This paper presents the use of CHWs to obtain reliable and quality data that can be used for planning as well as the use of generated health facility immunization data to increase immunization coverage and equity.
