When should I get the flu vaccine?

Page last updated 02 November 2018

The new seasonal flu vaccines usually become available in April. It’s important to have your flu vaccination in April or early May in order to give your body time to develop protection against the flu before we come into winter.

It usually takes about two weeks after you receive your flu vaccination for the body to develop immunity. Flu season can be unpredictable and can begin from late May through to October.
