Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study evaluated community-based interventions to increase vaccination coverage among underserved children aged 0-14 in 25 Indian communities from 2022 to 2025. Vaccination coverage improved from 68.4% to 89.7% through mobile clinics, health education, digital reminders, and stakeholder engagement. Mobile vaccination clinics were most effective, increasing coverage by 15.8%, while health education added 12.4%. Healthcare access, community participation, and parental education were key factors predicting vaccine uptake.
Key points
- Vaccination coverage increased from 68.4% at baseline to 89.7% by 2025
- Mobile vaccination clinics were the most effective single intervention, achieving a 15.8% increase
- Health education programs contributed a 12.4% increase in vaccination coverage
- Healthcare access (OR=2.84), community participation (OR=2.56), and parental education (OR=2.31) were significant predictors of vaccine uptake
- Combined community-based strategies reduced immunization disparities among underserved populations
Limitations
The document does not provide details on the comparison or control group structure, making it unclear whether improvements were compared to a control population or represent only within-group changes. The study also lacks information on intervention costs, sustainability beyond 2025, or whether gains were maintained after the study period.
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.
