Introduction: Australian and international guidelines recommend that healthcare workers (HCWs) have access to vaccines and serological testing to assure protection against vaccine-preventable diseases (VPDs). In March 2020, legislation was passed that mandates the vaccination of all Victorian HCWs. Whilst existing

Victorian policy supports this legislation, compliance with the guidelines is not well known. We sought to review current measles and hepatitis B immunity status, and historical influenza vaccine uptake of Victorian HCWs.

Methods: All Victorian public healthcare facilities were required to report HCW influenza vaccination uptake annually from 2014 to 2020. Small Victorian public healthcare facilities were required to also complete a point prevalence survey of HCW hepatitis B immunity status in 2016-2017 and HCW measles immunity status in 2017-2018. Facility-level aggregate data were captured regarding compliance with vaccination programs.

Results: During the study period, overall rates of HCW influenza vaccination uptake increased each year, culminating in a rate of 93% in 2020. HCW hepatitis B immunity in 2016-2017 was 59.1% and HCW measles immunity in 2017-2018 was 67.1% -‘Unknown’ status was reported in 21.3% and 29.1%, respectively.

Conclusion: HCW compliance with recommended immunisation guidelines is notably higher for influenza than for measles and hepatitis B. Possible reasons for this include the inclusion of HCW influenza vaccination uptake as an annual key performance indicator for Victorian hospitals. Future policy directives for HCW vaccination should proceed with acknowledgement of the potential benefit of including a range of VPDs as performance indicators.
