Zero-Dose Vaccination Prevalence Among Children in Sub-Saharan Africa

Featuring results from a secondary analysis of Demographic and Health Survey data from 2015 to 2024, using a total weighted sample of 58,443 children aged 12–23 months. It assesses the prevalence, spatial patterns, and determinants of zero-dose vaccination in sub-Saharan Africa, finding a prevalence of 13.3%.

Use Cases

• Analyze the association between household wealth index and zero-dose vaccination prevalence using adjusted odds ratios.
• Map hot spot clusters of zero-dose vaccination in countries like Nigeria, Angola, and Ethiopia to identify priority intervention areas.
• Model the impact of maternal education level and antenatal care visits on zero-dose vaccination risk.
• Investigate the relationship between home delivery, tetanus toxoid vaccination status, and zero-dose vaccination outcomes.
• Assess the effect of media exposure and perceived distance to health facilities on vaccination coverage in rural versus urban residences.

Strengths

• Analysis is based on a large, weighted sample of 58,443 children from multiple countries.
• Study employs multilevel spatial analysis to identify geographic clusters and determinants.
• Results include specific statistical measures like adjusted odds ratios with 95% confidence intervals for multiple factors.

Limitations

• The dataset is a secondary analysis summary, not the raw survey microdata, limiting granular exploration.
• Temporal coverage from 2015 to 2024 may not reflect the most current conditions post-2024.
• The 1.4 MB file size suggests the dataset contains aggregated results or a small subset of variables.
