Community-Based Interventions For Enhancing Vaccination Coverage Among Underserved Pediatric Populations

Abstract

Background: Vaccination is one of the most effective public health interventions to prevent infectious diseases among children. However, vaccination coverage rates are lower among underserved pediatric populations because of barriers including lack of access to healthcare, socioeconomic factors, lack of health literacy, and logistical issues. Objective: To assess the impact of community-based interventions on vaccine coverage in underserved pediatric populations and to determine the major factors driving vaccine uptake. Methodology: A longitudinal community intervention study in 25 underserved communities in 2022-2025 with 4,500 children aged 0-14 years. Intervention strategies involved community health education, mobile vaccination clinics, digital reminder systems, and local stakeholder engagement. Descriptive statistics, logistic regression and trend analysis were used to analyze vaccination records, household surveys and healthcare databases.  Findings: Vaccination coverage improved significantly from 68.4% at baseline in 2022 to 89.7% in 2025. Mobile vaccination clinics were the most effective, resulting in a 15.8% increase in coverage, followed by health education programs (12.4%). Logistic regression analysis showed that significant predictors of vaccine uptake were healthcare access (OR = 2.84), community participation (OR = 2.56) and parental education (OR = 2.31).  Conclusion: Community-based interventions resulted in significant increases in vaccination coverage and reductions in immunization disparities among underserved pediatric populations. Innovative educational, technological and outreach-based strategies can improve vaccine access and foster sustainable outcomes for public health.
