Associated Factors with the Child’s Fully Immunized in the Tambacounda Health District (Senegal)

To improve vaccination coverage among children under one year of age in the Tambacounda health district, a household survey was carried out among mothers or babysitters. The objective was to study the factors related to child’s fully immunized in children aged 12 to 23 months. The cross-sectional, descriptive and analytical survey was carried out during the month of April 2019. A multistage cluster survey selected a sample of 657 mothers and babysitters. The data was collected using a questionnaire made from the World Health Organization reference guide. Data entry and analysis were done with Epi Info software and R. Among the women surveyed, biological mothers were the most representative (96.9%). In the series, 74.1% had a good knowledge of the age for initiating vaccination, 78.2% knew the number of contacts. The vaccination record of the children was available in 92.2%, and 71.0% of them had presented an adverse event. The proportion of children fully immunized was 41.0%. Complete childhood vaccination was positively associated with income-generating activity in women (0R = 2.4) and the short distance (<100 m) between home and place of vaccination (OR = 1.5). It was also improved by having a qualified health worker as a vaccinator (OR = 1.4) satisfaction in relation to visit (OR = 2.0), the advice given by the vaccinator (OR = 1.7) and the fixing of the date of the next vaccination appointment (OR = 2.5). The implementation of a good strategy for improving the quality of immunization services is an important element for strengthening immunization coverage in the Tambacounda health district.
