Respiratory viruses are beginning to circulate more widely as Australia heads into winter. Influenza cases are picking up earlier than expected, and COVID-19 is continuing to circulate – often underestimated, but still capable of causing serious illness.
Public health experts are encouraging people to take a simple, evidence-based step to reduce their risk: taking your COVID-19 booster at the same time as your annual flu vaccination.
Professor Heidi Drummer, Burnet Deputy Director of Impact, and Scientific Director for Research Translation, says combining both vaccinations in one appointment is a simple but powerful way to improve protection for everyone.
“With COVID-19 booster uptake still low, many people are heading into winter with reduced protection at a time when respiratory viruses are spreading more easily,” she said.
“Getting your COVID-19 booster at the same time as your flu vaccine is a simple way to protect yourself against both viruses this winter. It’s safe, effective, and it’s practical.”
Early data suggest influenza is returning with force. More than 28,000 confirmed influenza cases have been recorded following a 2025 season where flu-related deaths reached a 25-year high.
When influenza and COVID-19 circulate at the same time, the impact can extend beyond individual illness. Increased hospital admissions place a strain on healthcare services, particularly during winter peaks.
Burnet modelling shows that increasing uptake of both vaccines, especially when delivered together, could help reduce severe outcomes and ease pressure on hospitals.
Vaccination remains one of the most effective tools we have to prevent serious illness.
While no vaccine offers complete protection from infection, both influenza and COVID-19 vaccines significantly reduce the risk of complications, hospitalisation and death.
This World Immunisation Week is a timely reminder that one appointment could provide broader protection when it matters most.
