When is the best time to get the flu vaccine?

Page last updated 21 February 2019

Influenza season in Australia usually peaks in August or September each year. Optimal protection from influenza vaccination occurs in the first 3-4 months following vaccination.

Therefore it is recommended to vaccinate when the national program starts, which is generally in late April. However as influenza continues to circulate, it is never too late to vaccinate.

If you are travelling to the northern hemisphere throughout their peak flu season, you should speak to your health professional about additional vaccination options.

Remember that it is always important to speak with your doctor about Influenza vaccination for you and your family.
