Chief Health Officer Advisory – Expanded access to the Japanese encephalitis vaccine for people visiting high-risk areas

Japanese encephalitis is a rare but potentially serious infection that is spread through mosquito bites.

High-risk areas in regional Victoria are experiencing a prolonged mosquito season this year due to recent flooding in parts of northern Victoria.

Eligibility to receive a free Japanese encephalitis vaccine has been temporarily expanded until 30 June 2026 to include people who plan to visit any of the 24 high-risk local government areas in Victoria for outdoor recreation.

People at increased risk of mosquito bites are advised to stay protected by getting vaccinated, if eligible, and following mosquito-bite prevention advice, especially this Easter and in the coming months.

Speak to your doctor or local immunisation provider to check if you are eligible for the free vaccine, including if you plan to visit any of the high-risk local government areas.

For more information on Japanese encephalitis and vaccine eligibility, including a list of all eligible local government areas, visit Japanese encephalitis.
