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.
