What is Super-K? Is it just the flu?

4th Jun 2026

As flu season returns in 2026, you may have heard about a strain of influenza A being referred to as “Super K.” While the name may sound concerning, it highlights an important reality: the flu virus changes every year.

New flu season, new flu virus strain, new flu shot

Each year, the flu virus changes and 2026 is no exception.

Health experts have identified a strain of influenza A, sometimes referred to as “Super K,” currently circulating in Australia. Because of these changes, the flu vaccine is reviewed and updated each year to target the strains most likely to spread during the season. The 2026 vaccine has been developed to reflect these current strains.

Why get vaccinated each year?

  • Flu strains change from year to year
  • Protection from the flu vaccine can decrease over time, with optimal protection lasting around 3-4 months after vaccination
  • This year’s vaccine is designed for this year’s flu season

When should you get vaccinated?

Flu vaccines are available now, and it takes around two weeks to build protection. Getting your flu shot can help ensure you are protected ahead of the peak flu season.
