Factors affecting the willingness of nursing students to receive annual seasonal influenza vaccination: A large-scale cross-sectional study

Abstract

Nursing students are at high risk of exposure to vaccine-preventable diseases such as seasonal influenza. However, due to the limited number of studies conducted in this area, the prevalence and factors affecting annual seasonal influenza vaccination (ASIV) uptake remain unclear. This was a large-scale cross-sectional survey study conducted among 902 nursing students in different years of study. The questionnaire was developed based on the Health Belief Model (HBM), and logistic regression was used to determine the predictors of ASIV uptake. The results of our study reveal that only 15.2% of nursing students declared having the vaccine in the previous year, and that ASIV uptake was self-reported. ASIV uptake was associated with perceived susceptibility (odds ratio=2.76), perceived seriousness (odds ratio=2.06) and perceived barriers (odds ratio=0.50). The odds of receiving ASIV were 17.96times higher for those participants having had ASIV at least once than those who had not received ASIV in the previous five years. In addition, the odds of receiving ASIV were 4.01times higher for master’s than undergraduate students. Our study concludes that the ASIV uptake among nursing students is low. In order to increase vaccination uptake in subsequent years, future studies should promote vaccination based on HBM, focusing on nursing students in undergraduate studies by emphasizing not only vaccination knowledge, but also their social responsibility to protect patients. Influenza vaccination can be viewed as an ethical professional responsibility and a patient safety issue, as well as being an infection control strategy.
