Factors Influencing DPT Immunization Completion among Children: Insights from Nakawa Division, Kampala, Uganda

Abstract

This study investigates the factors influencing DPT (Diphtheria, Pertussis, Tetanus) immunization completion among children aged 4–23 months in Nakawa Division, Kampala, Uganda. Utilizing a descriptive cross-sectional design with both qualitative and quantitative methodologies, data were collected from 271 participants using researcher-guided questionnaires. The analysis revealed a high DPT immunization completion rate of 94%, meeting WHO targets. Significant factors associated with completion included caretaker age, religion, and attitude toward vaccine safety and acceptability, as well as health service factors like distance to the facility, ANC attendance, convenience of immunization days, and vaccine availability. However, child-related factors such as age, gender, and birth order showed no significant association. These findings underscore the importance of targeted interventions to address caregiver perceptions and improve health service delivery for sustained immunization coverage.
