Background: Immunization is said to be the most effective public health intervention to prevent morbidity, complications, and mortality due to infectious disease among children. Due to the importance of vaccination in terms of infectious disease prevention, in terms of high cost-effectiveness ratio, international organizations, governments, and donors have intensified efforts to increase immunization coverage globally. Despite the efforts, thousands of children remain unimmunized or not fully vaccinated worldwide.

Objective: To identify factors associated with incomplete immunization among children in Côte d’Ivoire.

Method:The 1998-1999 and 2011-2012 Côte d’Ivoire Demography and Health Survey (DHS) data were used in this study. The included 3878 children aged 12 to 59 months with 1326 children from 1998-1999 DHS, and 2552 children from 2011-2012 DHS. Descriptive analysis was performed. Spearman’s correlation coefficient was computed to examine the relationship between variables. Univariate analysis was performed to examine the association between the dependent variable (incomplete immunization) and each independent variable using logistic regression. Variables with a p-value less than .05 in the univariate analysis were included in the multivariate analysis. Multivariate analysis was performed to determine predictors of immunization status using logistic regression (stepwise method).

Results: About 42.7% and 50.1% of Côte d’Ivoire were not fully immunized in 1998-1999 and 2011-2012, respectively. Child birth place, mothers’ access to media, mothers’ literacy, place of residence, and religion were the best predictors of incomplete immunization.

Conclusion:Health authorities in Côte d’Ivoire should take into account these immunization status predictors in order to address the issue of incomplete immunization.
