Factors associated with pentavalent vaccine coverage among 12-23-month-old children in Afghanistan: A cross-sectional study.

Penta3 coverage among 12-23-month-old children improved but was still lower than the target. Primary education should be provided to all children throughout the country. TV and radio are useful tools for providing health information. Mobile outreach programs and the establishment of new health facilities should be promoted to improve access to health service for all people in Afghanistan.
