Knowledge, attitudes and practices of Australian medical students towards influenza vaccination

Background: Annual influenza vaccination is recommended but not compulsory for healthcare workers in Australia, including medical students. A quarter of healthcare workers are estimated to have an influenza infection in any given year, with a subsequent transmission risk to colleagues and patients. During clinical placements, medical students are also at risk of influenza. While compliance with other vaccination requirements are high, influenza vaccine uptake of healthcare workers and medical students remain low globally. We aimed to explore medical students' influenza vaccination rates, attitudes, knowledge and intended practices at a large Australian university.

Method: A 35 item self-administered online survey was distributed to medical students enrolled at a large Australian university (UNSW Australia) in April/May 2014. The survey examined the knowledge, attitudes and practices of medical students towards influenza vaccination and identified factors associated with vaccine uptake.

Results: Of the 606 students, 53.8% (95%CI 49.8-57.8%) receiving their most recent influenza vaccine in 2014. Self-protection was the most common motivator (83%) and inconvenience (64%) the most common barrier to vaccination, despite access to on campus clinics. Students generally held positive attitudes to the influenza vaccine and vaccination recommendations, though some misconceptions existed. The majority (61%) were in support of mandatory influenza vaccination policies for medical students. Significant predictors of influenza vaccination included living on campus, clinical experience, awareness of vaccination recommendations and agreeing that vaccination was important for medical students, while those with perceived time constraints were less likely to be vaccinated.

Conclusion: Misconceptions and access to influenza vaccine were barriers to uptake of influenza vaccine by medical students. Medical programs need to emphasise the benefits of influenza vaccination in the protection of healthcare workers and patient safety across the medical education program. Our results suggesting majority support for mandatory influenza vaccination may represent a shifting perspective in the medical community.
