Full Immunization Coverage and Related Socio-Demographics Factors in Children Aged 12-23 Months Received in Albert Royer Hospital in Dakar, Senegal

Abstract

<i>Introduction</i>: Vaccination is one of the most effective and least costly public health interventions in the world. <i>Methods</i>: This is a cross-sectional, descriptive and analytical study of children aged 12-23 months received in consultation at the Albert Royer Children’s Hospital during the period from November 20, 2019 to January 20, 2020. Results: Boys accounted for 61.8% of children and 70.8% were at least 15 months of age. The average age of mothers was 29.2 years. They were not educated in 22% of cases. Almost all (95.2%) had received vaccination information. Just over half (51%) of mothers did not know how many vaccine contacts their child needs to make. Vaccination records were available in 88.7% of cases. Immunization coverage was complete in 62.9% of children. In multivariate analysis with step-down logistic regression, the only factor significantly associated with complete immunization coverage was the child’s rank in siblings (OR =1; p=0,04). <i>Conclusion</i>: Full immunization coverage for children aged 12-23 months received in pediatric emergency department consultations is low. The vaccination rate according to the specific vaccine is important with good retention for almost all multiple-dose vaccines between the first and third doses.
