Uptake and Completion of Human Papilloma Virus Vaccination by Adolescent Girls Attending Primary Healthcare Facilities in Soroti City, Northeastern Uganda; A Cross Sectional Study

Abstract

Introduction: Uganda adopted and implemented Human Papilloma Virus (HPV) vaccination since 2015 for adolescent girls aged 9-13 years for primary prevention of cervical cancer. However, the vaccine uptake and dose completion have remained relatively low national wide. Therefore, this study aimed at determining the uptake and dose completion of HPV vaccination and associated factors in Soroti city, Northeastern Uganda. Methodology: This was a cross-sectional study that employed quantitative methods of data collection and analysis. A sample of 287 adolescent girls aged 10-19 years were selected consecutively from four health centers in Soroti City between March and April 2024. Data was analyzed using Stata statistical software, version 15.0. Descriptive statistical analysis was performed to determine the level of HPV vaccine uptake and dose completion. Bivariate and multivariate analyzes were performed using modified Poisson regression with robust error estimates to determine association between independent factors and uptake and dose completion. Results were reported with a 95% confidence interval (CI) and factors whose P-Values were less than 0.05 were considered statistically significant. Results: Of the 287 adolescent girls, their mean age was 14 years (SD=2.9). Most of the participants were in school, 231(80.5%). Majority, 79 % (n=228) had never heard about HPV Vaccination. HPV Vaccination uptake among the study participants was suboptimal as only 58.8% (n=166) had received at least one dose whereas only 30% (n=86) had completed the two doses of the vaccine. The factors that were significantly associated with vaccination uptake were school enrollment status (P=0.022), religion (P=0.010), and awareness about HPV vaccine (P<0.001), while factors that were significantly associated with completion of HPV vaccination were: School enrollment status (P=0.046) and awareness about HPV vaccine (P=0.007). Conclusion: The uptake and completion of HPV vaccination in Soroti was suboptimal compared to WHO target of 90%. School enrollment status and awareness about HPV vaccine were factors significantly associated with HPV uptake and dose completion. Strengthening the school-based HPV vaccination program and creating awareness about HPV vaccination, in schools, at the health facilities and in the community may significantly improve the HPV vaccination and dose completion in the region.
