Mapping of DPT Vaccine Coverage in Africa Reveals Variations Among and Within Countries

Substantial variation exists in DPT coverage within and among African countries; mapping coverage is useful to identify areas of need.

Routine childhood vaccination contributes to child survival. But is this intervention reaching all children? To assess coverage with diphtheria-pertussis-tetanus (DPT) vaccine in Africa over time and space, investigators analyzed survey data (2000–2016) and used Bayesian geostatistical modeling to produce annual estimates of DPT coverage and dropout for children (aged 12–23 months) in 52 African countries (spatial scale, 5 km x 5 km). Investigators calibrated data to results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017.

National coverage estimates inadequately portrayed subnational variation in DPT coverage. Coverage varied substantially within and among countries. Overall estimated coverage with third-dose DPT (…
