Assessment of Levels of Immunization and Factors Associated with the Non-completion Routine Immunization within (9-12 Months) Attending Primary Healthcare Centres in Ibadan North and South East, Nigeria

Immunization is designed to prevent transmittable diseases and it is an integral public medical intervention and an economical method to decline mortality and morbidity associated with transmittable diseases. This work attempts to determine the vaccine coverage and factors related to the non-completion routine immunization within babies (9-12 months) attending Primary Healthcare Centre (PHC) in Ibadan North and South East Local Government Areas, Oyo State. The descriptive cross-sectional study research design was employed for this work. Health belief model theory and multistage sampling procedures were applied to choose 422 participants from all the chosen PHCs in the study location. The results indicated that complete immunization coverage for all five childhood vaccines in both sites were low (69.5%) relative to the WHO stipulated guideline of 80%. Overall results revealed that the complete immunization coverage from the sampling site for children 12 months of age was 69.7% and 69.5% for children among 9–11 months. The findings of survey indicated that percentage of vaccine coverage reduces as child age increases. Mothers/caregivers’ knowledge of vaccination, perception concerning vaccination and socio-demographic factors like educational status, occupation, and monthly earnings were all statistically significantly correlated with complete immunization in children. This study concluded that knowledge and perception control behavior and disposition of mothers/caregivers towards vaccination. Thus, health personnel and health educators need to underscore the significance of vaccination and likewise seek to decry all the wrong believes and negative attitudes on vaccination.
