Key Points

  • To assess long-term trends in influenza vaccination coverage among healthcare workers in public sector residential aged care services from 2018 to 2025.
  • Analyzed annual influenza vaccination surveillance data from 165 to 177 public sector residential aged care services submitted to the state coordinating centre in Victoria, Australia.
  • Categorized staff vaccination status as vaccinated, medically contraindicated, declined, or unknown.
  • Stratified findings across pre-pandemic (2018–2019), pandemic (2020–2023), and post-pandemic (2024–2025) intervals.
  • Vaccination coverage rose during the COVID-19 pandemic and remained sustained above 97% from 2020 onward, with an exception in 2021.
  • Vaccine declination rates among staff dropped substantially and stayed at or below 0.4% starting in 2020.
  • Annual reporting included 165 to 177 facilities, accompanied by an overall increase in employed staff numbers during the post-pandemic period.
