Healthcare workers' perspectives on mandatory influenza vaccination: a scoping review

Background: Vaccination is efficacious at preventing influenza disease transmission, morbidity and mortality. Benefits of influenza vaccination for healthcare workers (HCW) are emphasized, yet vaccine uptake among HCW remains suboptimal. Mandatory vaccination programs may increase influenza vaccine uptake, however, attitudes and beliefs of HCW towards these mandates are not well known.Aims: This scoping review examined the attitudes and beliefs of HCW to ascertain the barriers and enablers to the implementation and acceptance of mandatory vaccination programs in healthcare settings.Design: Scoping review, guided by the PRISMA Extension for Scoping Reviews.Methods: Literature published between 2019 and 2023 was reviewed from five electronic databases, between June and October 2023.Data sources: Quantitative, qualitative and mixed-methods studies were obtained. Studies were limited to full-text English articles, published within peer-reviewed journals over the last five years. Data were extracted by both authors and documented using a modified version of the JBI's scoping review data extraction instrument, and analyzed thematically.Results: The original search yielded 319 articles. Forty-two articles were screened, with 10 studies included. Most HCW had negative views towards mandatory influenza vaccination, influenced by geographical location, age and discipline. The protection of patients and affordability/accessibility of vaccination were described as enablers to the acceptance of mandatory measures. The belief that mandatory vaccination was a violation of autonomy and misconceptions concerning influenza transmission, vaccine mechanism of action, side effects and effectiveness, were described as common barriers.Conclusions: Health services must carefully consider the context in which mandatory vaccination programs are implemented and employ strategies that incorporate education and promote vaccine accessibility, affordability and HCW autonomy. The quality of evidence retrieved was moderate to poor, with high heterogeneity between studies. Minimal Australian research was evident, limiting the generalisability of findings. These results should be interpreted with caution and further high-quality research is recommended.
