Rapid survey to determine the predictive factors of vaccination coverage in children aged 0 to 59 months in Guinea

Abstract

Background: The Expanded Program on Immunisation has made it possible to prevent more than 3 million deaths in children under 5 years. The objectives of this study were to estimate the vaccination coverage of children from 0 to 59 months and identify factors associated with incomplete vaccination coverage. Methods: A cross-sectional study was carried out in a dispensary in Conakry, Guinea between January and February 2020. Sociodemographic and vaccination information was collected from mothers of 380 randomly select children aged 0 to 59 months. Information on immunisation coverage was gathered from records vaccination cards and maternal reports. Logistic regression was used to identify factors independently associated with incomplete immunisation coverage. Results: Most (66.5%) children aged 12 months were up-to-date with their vaccinations. Factors associated with incomplete vaccination in this age group included: unavailability of vaccination cards (adjusted odds ratio [aOR] 7.58; 95% confidence interval [CI]: 2.56–22.44) and lack of prenatal consultation attendance (aOR 2.93; 95% CI: 1.15–7.48). In contrast only 19.8% (95% CI: 13.9–26.7) of children aged 12–59 months were fully immunised. Factors associated with incomplete vaccination coverage in children aged 12–59 months included high birth order (aOR 10.23; 95% CI: 2.06–19.43), and lack of prenatal consultation attendance (aOR 5.34; 95% CI: 1.48–19.23). Conclusion: Child immunisation coverage is low in Guinea. These results highlight the need to develop strategies based on an integrated approach to overcome obstacles to childhood immunisation in Guinea.
