Since last 100 years, immunization rate is one of the best public health outcome and service indicators. However, the immunization system is still imperfect; there are many countries that still have unvaccinated children. Parental decisions regarding immunization are very important to improve immunization rate. The aim of this study is to evaluate the association between parental knowledge-practice (KP) regarding immunization with family and immunization providers’ factors.
This is a prospective cross-sectional study design. Immunization knowledge and practices among 528 Iraqi parents were evaluated through validated questionnaire. Familial data and immunization provider’s characteristics were collected from parents through interview.
More than half of respondents/study population (66.1%) have adequate knowledge- practice scores. Significant associations were noted for knowledge-practice groups with father’s education level, mother’s education level, mother’s age at delivery, number of preschool children, parents gender, family income, provider types, and birth place (p < 0.05).
Immunization campaigns and awareness are required to improve parents’ knowledge and practice regarding immunization. The study results reinforce recommendations for use of educational programmes to improve the immunization knowledge and practice.
