<p>The mean age of mothers and children was 27±6 years and 19±3 months, respectively. The coverage of fully vaccinated children was 34.45%. The long waiting period for mothers favoured incomplete vaccination of children after adjustment for insecurity in bivariate logistic regression with an ORa[IC95%]=24.43[2.80-213.15] and a p=0.0038. Unawareness of the importance of vaccination (ORa[CI95%]=9.34[2.15-40.58], p=0.0029), knowledge of fewer than five target diseases of the expanded program of immunization (ORa[CI95%]=3.80[1.42-10.17], p=0.0078), mothers with no income (ORa=[CI95%]=2.96[1.68-5.21], p=0.0002), long waiting time (ORa=[95% CI]=2.38[1.52-3.72], p=0.0002), home delivery (ORa[95% CI]=2.26[1.46-3.50], p=0.0002) and failure of vaccinators to conduct educational talks (ORa=[95% CI]=1.79[1.15-2.78], p=0.0092) were statistically associated with incomplete vaccination of the children</p>
