Influenza vaccination uptake and barriers among Yarmouk University students: A cross-sectional study

Problem Considered Influenza remains a significant public health concern, and vaccination is the most effective preventive strategy. However, misconceptions may limit vaccination among young adults. This study assessed influenza vaccination history, knowledge, and barriers among students at Yarmouk University, Jordan. Methods A cross-sectional study using convenience sampling was conducted among 1,007 Yarmouk University students through an online survey between October and December 2024. Data were analyzed using descriptive statistics, chi-square tests, and multivariable logistic regression. Results More than half of participants (56.2%) reported limited self-perceived knowledge regarding influenza vaccination, and only 27.9% were aware that influenza vaccination is recommended annually. Overall, 47.3% reported having ever received an influenza vaccine, whereas only 5.0% (24/476) of those previously vaccinated reported annual vaccination. Commonly reported barriers included perceiving influenza as not serious (24.0%), lack of time (19.8%), and concerns about side effects (19.3%). In multivariable analysis, male gender, limited self-perceived knowledge, and healthcare provider recommendation were independently associated with previous influenza vaccination. Male students had higher odds of previous vaccination than female students (adjusted OR=1.99, 95% CI 1.39–2.84), whereas students with limited self-perceived knowledge had lower odds than those reporting some information (adjusted OR=0.60, 95% CI 0.43–0.85). Healthcare provider recommendation was also associated with higher odds of previous vaccination (adjusted OR=1.55, 95% CI 1.11–2.16). Conclusion Influenza vaccination history among Yarmouk University students remains suboptimal, while annual vaccination is particularly uncommon.
