Immunization is a cost-effective approach to reduce morbidity and mortality associated with infectious diseases and still remains one of the most important public health interventions in developing countries. The main objective of the study was to assess knowledge, attitude, satisfaction and barriers affecting utilization of immunization services among women attending clinic in a tertiary institution in Edo state, Nigeria. The study utilised a descriptive cross-sectional study, using a structured face to face interviewer administered questionnaire with open and closed ended questions to obtain information on knowledge, attitude, practice and satisfaction of immunization services amongst 300 mothers attending the immunization clinic. Results from the study shows that 187 (62.3%) of the mothers had good knowledge of immunization, 238 (79.3%) of the respondents had positive attitude towards immunization, about half 66.7% didn’t vaccinate their children because they didn’t think it was necessary while majority were satisfied with immunization services received. Level of education, place of delivery was some of the factors affecting mother’s knowledge of immunization. The knowledge of immunization among the mothers was high, there was fairly positive attitude towards immunization and majority were satisfied with immunization services. Developing and implementing age specific maternal and child health promotion campaigns targeting specific age groups may increase utilization of MCH services among women of reproductive age in the country and thus improve MCH outcomes.
