Childhood immunization remains one of the most effective public health interventions for preventing disease and reducing child mortality. Yet, many children across Nigeria still fail to receive complete vaccination coverage during their early years. A recent study published in the African Journal of Health and Social Sciences examines the patterns and predictors of incomplete childhood immunization among children aged 12–23 months in Abuja, Nigeria.
The study by Eric Okorie Nwaze and colleagues highlights how social, healthcare, and environmental factors continue to influence vaccination uptake and contribute to preventable health risks among children.
Using a community-based cross-sectional study design, the researchers surveyed 350 caregivers of children aged 12–23 months across Abuja. Data were collected through structured interviewer-administered questionnaires and verified using immunization cards to assess whether children had received all vaccines recommended under Nigeria’s national immunization schedule.
The findings revealed that 21.7% of children had incomplete immunization, meaning they missed one or more recommended vaccines before the age of 12 months. The study also found particularly low coverage for the second dose of the measles vaccine, with only 28% of eligible children receiving it.
One of the study’s most important findings was the strong relationship between maternal healthcare engagement and childhood immunization completion. Children whose mothers did not receive antenatal tetanus toxoid vaccination were significantly more likely to have incomplete immunization coverage.
The researchers identified maternal tetanus toxoid vaccination as one of the strongest independent predictors of childhood immunization completion, suggesting that improving antenatal healthcare utilization could also improve child vaccination outcomes.
The study also found that rural residence increased the likelihood of incomplete immunization. Families living in rural communities often face barriers such as limited healthcare access, transportation challenges, inadequate healthcare infrastructure, and lower exposure to public health information.
Interestingly, regular television exposure appeared to have a protective effect. Caregivers who watched television daily were less likely to have children with incomplete immunization, suggesting that media access may improve awareness of vaccination schedules and healthcare information.
Other factors associated with incomplete immunization included maternal education levels, parity, place of delivery, and healthcare utilization patterns.
The findings reinforce concerns that inequalities in healthcare access, education, and health communication continue to shape child health outcomes in Nigeria.
Importantly, the researchers argue that improving vaccination coverage requires more than vaccine availability alone. Strengthening maternal education, promoting facility-based childbirth, increasing antenatal care attendance, and improving healthcare communication strategies may all play important roles in reducing missed vaccinations.
The study also highlights the broader public health importance of immunization in preventing vaccine-preventable diseases, reducing childhood mortality, and strengthening community health resilience.

1. Strengthen Maternal Healthcare Services
Improving antenatal care attendance and maternal vaccination programs may significantly improve childhood immunization completion rates.
2. Expand Immunization Outreach in Rural Communities
Targeted healthcare interventions are needed to improve vaccine access and healthcare delivery in underserved rural areas.
3. Increase Public Health Awareness Through Media
Television, radio, and digital health campaigns can help improve caregiver awareness about vaccination schedules and child healthcare.
4. Promote Facility-Based Deliveries and Child Health Education
Healthcare facilities should integrate maternal education and immunization counseling into routine maternal and child health services.
The study ultimately demonstrates that incomplete childhood immunization remains a major public health challenge in Nigeria. Addressing the social, educational, and healthcare barriers influencing vaccine uptake will be critical to improving child survival and preventing avoidable disease outbreaks.
