Please see the WA Immunisation Schedule and refer to the Influenza chapter on the Australian Immunisation Handbook (external site) for detailed advice, including vaccine dosage, and contraindications.

Timing of influenza vaccination

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.

For a brief summary of General Practice and hospital emergency department sentinel surveillance data on influenza-like illness, subscribe to Virus WAtch (a weekly electronic publication by CDCD and key collaborators).  For Australian Influenza Surveillance Reports, visit the Australian Government Department of Health and Aged Care website (external site).

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.
