If you live or regularly work in a flood impacted area, it is recommended by NSW Health that you get vaccinated against Japanese encephalitis virus.

In NSW, wet conditions and stagnant water after floods creates a breeding ground for mosquitoes and can contribute to an increase in Japanese encephalitis virus (JEV) cases.


You may be eligible for a free vaccination if you

  • are aged 2 months and older
  • live or routinely work in certain local government areas, and you
    • regularly spend time outdoors 
    • are experiencing homelessness
    • are living in conditions with limited mosquito protection (for example tents, caravans, dwellings with no insect screens), or
    • are engaging in outdoor flood recovery (clean-up) efforts, including repeated professional or volunteer deployments.

Visit NSW Health to check your eligibility.

How to access

Speak to your General Practitioner (GP), pharmacist or Aboriginal Medical Service about getting a vaccination.

Note: Some providers may charge an administration or consultation fee. Be sure to check if this applies to you.
