Coverage and factors associated with complete polio vaccination among Indonesian children aged 0-18 months

Introduction: The polio vaccine is one of the vaccinations required for all children by the government of Indonesia. However, polio vaccination coverage has not yet reached its maximum. This study aimed to analyze the coverage and factors associated with complete polio vaccination among Indonesian children aged 0-18 months. Methods: A cross-sectional design used observation data drawn from the Demographic and Health Survey 2017. A total of 5378 respondents were obtained through the two-stage stratified cluster sampling technique. The questionnaire included DHS Questionnaire Phase 7. The variables include the mother's age, education level, wealth quintile, residence, number of living children, marital status, visit to a health facility, health insurance, whether currently employed, household head gender, and complete polio vaccination. The data were analyzed using chi-square and binary logistic regression. Results: Based on IDHS 2017, 35.83% of Indonesian children aged 0-18 months received the complete polio vaccination. The factors associated with complete polio vaccination were mother's age 15-24 years old, secondary education level, wealth quintile, visit to a health facility, and current employment. The number of living children, marital status, health insurance, and household head gender were not associated with complete polio vaccination. Conclusion: To achieve the target coverage of the polio vaccination, the Indonesian government needs to consider factors such as the mother's age, education level, wealth quintile, recent visits to a health facility, employment and other factors. In addition, optimization by increasing the availability of information on the importance of polio vaccination is needed.
