Factors Associated with Access to Under-Five Immunization Usage by Mothers in Ota, Ogun State, Nigeria

The paper examined factors associated with mothers' access to under-five (U5) immunization use in the study area. The study used a 2017 cross-sectional survey on child morbidity and survival data. This study was based on cross-sectional hospital-based survey data, and 1350 pregnant women who attended antenatal care, including immunization clinics for their children, during the survey period were interviewed. A multi-stage sampling technique was deployed in the design to select the respondents. The study obtained information from the respondents on demographic characteristics, immunization, and quality of healthcare services. The linear regression results showed that the place of delivery (p = 0.000), who assisted the respondents on the delivery of last child (p = 0.002), who takes care of the child in respondents absence (p = 0.000), birth spacing between last child and present pregnancy (p = 0.000), type of household waste disposal practice (p = 0.000) and knowledge about child preventable diseases (p = 0.000), are significant to the outcome variable, the immunization standing of last-child, a proxy dependent variable for child immunization status. The study recommends health education for stakeholders and retraining for healthcare workers to provide better quality child immunization services in the study area.
