Providers should consider vaccinating in the months prior to the peak influenza season, which typically spans July to October in WA. Influenza vaccination should continue to be offered while the influenza virus remains in circulation, and a valid vaccine is available.

Optimal protection against influenza occurs within 3 to 4 months following vaccination. During the influenza season, look for opportunities to provide influenza vaccination to persons at increased risk of influenza during visits for routine medical care.
If a person had a 2023 formulation influenza vaccine in late 2023 or early 2024, they are still recommended to receive a 2024 formulation influenza vaccine.
People who are planning international travel should ensure they have had a 2024 influenza vaccination before departure.
