Introduction: In recent years, several epidemics, especially measles, had been notified in some local governments of Benin such as the one of Djougou.

Objectives: This study aims to assess vaccination coverage and identify immunization system factors associated with children immunization status.

Methods: It was a cross-sectional, descriptive and analytical study. It had been conducted from 29th to 31st August, 2013 and involved 410 children aged of 12 to 23 months and their mothers/minders. The study also focused on the officers of 13 immunization services. Those respondents were randomly selected through cluster sampling in 30 villages of the local government of Djougou.

Findings: Coverages with tuberculosis vaccine (BCG), with vaccines against diphtheria, tetanus, pertussis, haemophilus influenzae b, and viral hepatitis B 1st, 2nd and 3rd doses (DTP1 - Hep1 - Hib1, DTC2 - Hep2 - Hib2, DPT3 - Hep3 - Hib3) and measles vaccine were respectively 96.30%, 92.90%, 89.00%, 84.60% and 72.00%. Concerning the immunization status, 29.02% of the children were not fully vaccinated. After analysis, six immunization system-related factors associated with immunization status were identified.

Conclusion: About one out of three children was not completely vaccinated. These results may explain the occurrence of measles epidemics recorded in the local government.
