Aim: Australian healthcare personnel (HCP) are a vulnerable, yet essential cohort prioritised for seasonal influenza vaccination (SIV). Despite extensive SIV programs, and other health protective behaviours, high levels of influenza exposure contribute to almost 23% of HCP being infected each season. In that context, understanding determinants that maximise SIV uptake among HCP is an important but under-explored area. Subject and methods: We conducted 14 semi-structured interviews with Australian HCP, primarily those most involved with vaccination procedures, including nurses, midwives, pharmacists, and medical practitioners. The question guide development was based on constructs from the Triandis Theory of Interpersonal Behaviour and an integrative review. All interviews were transcribed verbatim with the application of Braun and Clarke’s reflexive thematic analysis to identify and explore pertinent themes. Results: Six distinct but inter-related themes were associated with HCP seasonal influenza vaccination behaviour. Most significantly, professional responsibility and identity appeared highly associated with positive vaccine intention, followed by vaccination convenience and ease of access. Protection, habit, risk perception, and experience and knowledge were also found to influence HCP decision making around SIV. Vaccination complacency, not hesitancy, was described as impeding the progression of vaccination intention (acceptance) to vaccine behaviours (uptake). Conclusion: Findings suggest interventions that foster professional identity, leverage camaraderie and a ‘duty of care’ to protect others may enhance SIV intention. While improved access to SIV in the workplace could promote positive vaccination behaviour, particularly if triggers or nudges are applied to prompt the vaccination habit in the presence of SIV acceptance.

Background/Objectives: Qualitative research suggests there may be identifiable characteristics that form a health professional (HCP) archetype associated with habitual seasonal influenza vaccination (SIV). However, the validity of this archetype requires further investigation, ideally within a theoretical framework that can elucidate this association and its generalisability to other vaccines. This study aims to confirm key HCP archetype characteristics associated with SIV, as informed by prior qualitative research findings, and test the generalisability of the association between this archetype and SIV to COVID-19 vaccine acceptance. Method: A cross-sectional survey was designed and distributed to an Australian HCP sample consisting of practicing nurses, midwives, pharmacists, and medical practitioners. The anonymous online survey measured key characteristics that predict vaccination behaviour and intention. Results: Most participants (n = 173) demonstrated habitual SIV behaviour (77.91%) associated with the intention to vaccinate in the future. Survey findings supported the HCP archetype, as key constructs were associated with vaccination intention and behaviour, including heightened professional responsibility, vaccine confidence, and protection of self and patients. Furthermore, results suggested progressing vaccination intention to behaviour, overcoming vaccine complacency, is possible through the provision of free, accessible vaccination services. These critical factors were broadly generalisable to the COVID-19 vaccine. Conclusions: A vaccination-positive HCP archetype, supported by access to free, convenient vaccination services, was associated with the likelihood of future vaccination behaviour, including in future pandemic response scenarios. However, it will be important to ensure that HCP vaccine knowledge gaps are minimised to enhance trust in this cohort to enable broad success.
