Why this research matters now
The findings identify socioeconomic, seasonal, community-mobilization, and service-delivery factors relevant to yellow fever vaccination access in the studied DRC settings. The authors indicate that outreach, community mobilization, and adaptation of services to environmental conditions may support more equitable coverage.
Structured evidence summary
Research question
The study examined systemic barriers associated with failure to meet yellow fever vaccination coverage targets among children aged 9–23 months in the Democratic Republic of the Congo.
Study design
This was an analytical cross-sectional survey conducted from January through August 2024. Logistic regression was used to assess factors associated with lack of vaccination coverage.
Population and setting
The study included 1,247 children aged 9–23 months and their mothers or guardians across 156 health areas in six provinces of the Democratic Republic of the Congo.
Main findings
Reported yellow fever vaccine coverage was 80.8%. The abstract reports associations between lower coverage and maternal occupation, precarious housing, having at least two children in the household, the rainy season, absence of community awareness activities, and reliance on a fixed vaccination strategy, with adjusted odds ratios ranging from 1.42 to 5.92.
Public-health relevance
The findings identify socioeconomic, seasonal, community-mobilization, and service-delivery factors relevant to yellow fever vaccination access in the studied DRC settings. The authors indicate that outreach, community mobilization, and adaptation of services to environmental conditions may support more equitable coverage.
Important limitations
The study used a cross-sectional design and reports associations, so the supplied abstract does not establish temporal or causal relationships. This summary relies on the supplied single-article abstract and metadata; the original paper is required for decision-grade interpretation of sampling, measurement, analysis, and generalizability.
GIDS interpretation
The article is discoverable in the supplied evidence as a yellow fever vaccination study from the Democratic Republic of the Congo, with relevance to vaccination and climate or environmental context. It provides article-level context only and does not confirm or characterize any live surveillance signal.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
Evidence relationships
This article has 9 auditable classifier relationships to diseases, places, topics, and study design.
