It’s Not Over: Why Australia’s Early High Flu Season is Warning Sign for What’s to Come This Winter (and How to Protect Yourself))



Australia’s flu season arrived early this year and is setting records for all-time high cases. This may have an enormous impact on the United States, as well as worldwide.



As we move into the fall and winter months, there’s a high probability that many countries – especially the U.S. – may mean a serious flu season this year.

This year, the Southern Hemisphere influenza season arrived early in 2022, with Australia’s confirmed flu cases hitting an all-time high in May, more than double the month’s previous record set in 2019.


While a decrease in influenza-like illness has been noted since July 2022, Australia’s influenza cases may be an early warning sign for the U.S. as Southern Hemisphere influenza surveillance has historically been a strong predictor of influenza activity for the Northern Hemisphere flu season.


Notably, Australia’s flu season runs from May through September, providing a sense of what is possible for the U.S. season. In addition, Australia has also seen a profound impact on teenagers and younger populations who have had lower vaccination rates. 60% of flu hospitalizations have been children under 16, with adults over 65 only making up 18.5% of hospital admissions, which is not the norm.2


By now, many of us know that the Centers for Disease Control and Prevention (CDC) recommends that all eligible individuals six months and older receive an annual influenza vaccine as the best way to prevent seasonal influenza and its potentially serious complications, such as hospitalizations and deaths. 3


Despite the many potential benefits, only about half of Americans get an annual flu vaccine, and in fact, during the 2021/22 season, we saw a significant drop in influenza vaccinations compared to record vaccinations the year before. 4,5

As we approach the 2022/23 flu season, getting the word out is more important than ever for several reasons:


  • Flu vaccination and COVID-19 booster programs are expected to overlap this fall and it is critical that we do everything we can to ensure that people do not neglect getting vaccinated against influenza.



Dr. Lisa Doggett, a family practitioner, and Dr. Gregg Sylvester, CSL Seqirus Chief Health Officer, joined me to discuss these trends, more on the upcoming flu season, and the importance of flu vaccination for all eligible individuals, including children six months and older.
