Japanese Encephalitis Vaccination (JEV)
Japanese encephalitis is a rare but potentially serious infection caused by the Japanese encephalitis virus (JEV). It spreads to people through the bite of an infected mosquito.
Most people who are infected have no symptoms. Fewer than 1 in 100 become unwell. In those who develop inflammation of the brain (encephalitis), the illness can be fatal or leave lasting problems with the brain and nerves. There is no specific treatment.
Vaccination, along with avoiding mosquito bites, is the best protection. A free vaccine is available for people at higher risk in some states and territories.
Free JE vaccination is available at participating TerryWhite Chemmart pharmacies in NSW, QLD, SA, VIC and the ACT. Check your eligibility below.
About the vaccines
Two JE vaccines are used in Australia. Your pharmacist will check which one suits you.
| Imojev | JEspect | |
|---|---|---|
| Type | Live, weakened virus | Inactivated (not live) |
| Doses in the first course | One | Two |
| Age | 9 months and over | 2 months and over |
| Pregnancy or weakened immune system | Not suitable | Suitable |
| When protection develops | About 14 days after the dose | About 28 days after the second dose |
Keep protecting yourself from mosquito bites after vaccination. No vaccine is 100% effective, and mosquitoes carry other infections, such as Ross River virus, that have no vaccine.
Do I need a booster? Some people who are still at risk need a booster 1 to 2 years after their first course. This includes people vaccinated before they turned 18, during pregnancy, or while their immune system was weakened. Your pharmacist can check whether you need one and whether it is free in your state.
Not eligible for a free vaccine? You can still get the JE vaccine privately. It is also recommended for some people travelling to parts of Asia and Papua New Guinea. Ask your pharmacist about cost and availability, and aim to finish vaccination at least 2 weeks before you leave.
JEV vaccination during pregnancy and breastfeeding1
Pregnancy. If you are pregnant and at increased risk of JE, vaccination with JEspect is recommended. Infection in the first and second trimesters has been linked to miscarriage. No adverse pregnancy outcomes have been linked to JEspect.
Breastfeeding. JEspect is also the recommended vaccine while breastfeeding for people at increased risk. There is little information on its use during breastfeeding.
Imojev is a live vaccine. It must not be given during pregnancy and is not recommended while breastfeeding.

Learn more about Japanese encephalitis
Japanese encephalitis virus spreads through the bite of an infected mosquito. It does not spread from person to person, and you can't catch it from eating pork.
Most infections cause no symptoms. When symptoms appear, they usually start 5 to 15 days after the bite and can include:
- fever
- headache
- nausea and vomiting
- muscle aches.
In severe cases the virus affects the brain. Get medical help urgently if someone has:
- a severe headache with a stiff neck or sensitivity to light
- confusion, drowsiness or a change in behaviour
- weakness or trouble moving
- a seizure.
