This study explores influenza vaccination uptake, beliefs, vaccine hesitancy, and influenza-related absenteeism among undergraduate nursing students. Using a descriptive cross-sectional survey design, data was collected via an online questionnaire assessing vaccination status, knowledge, attitudes, and illness-related absenteeism. The findings reveal a generally high vaccination uptake and positive attitudes toward the vaccine. However, some students still reported concerns regarding vaccine safety, side effects, accessibility, and effectiveness. Ultimately, the study emphasizes the importance of evidence-based vaccination education, institutional support, and infection prevention programs to reduce absenteeism and promote safer healthcare practices among future nurses.
