When should people get vaccinated?

Answer: 

Vaccinate as soon as possible after the vaccine becomes available (vaccine is usually available from March).  It takes up to two weeks to develop immunity.  Ideally, you should be vaccinated before the main influenza activity in May to September.  High risk individuals can be immunised any time during the influenza season.  The vaccine is only free until the 31 December.
