The influenza vaccine (also called the flu vaccine) is used to prevent infection caused by the influenza (flu) virus. The flu can cause serious illness, especially in young children, older adults and people with long-term health problems, but anyone can become seriously ill from the flu virus.
Even if you're not feeling sick, you could still be infected with the flu virus and pass it on to others.
The flu vaccine is available from 1 April each year, before winter starts. We recommend everyone over 6 months old gets immunised against flu every year.
If you have a tamaiti (child) under 9 years old, talk to your vaccinator about whether they may need 1 or 2 immunisations (4 weeks apart) depending on if they have had a flu vaccine before.
