Japanese Encephalitis Vaccine in Point Cook
Japanese encephalitis is a viral infection spread by mosquitoes. Most people who are infected never feel unwell, but a small number develop brain inflammation that can cause lasting damage. Our GPs in Point Cook can tell you whether a Japanese encephalitis vaccine suits your plans and give it at Juniper Avenue Medical Centre.
Where Japanese encephalitis occurs
The virus is regularly found in parts of Asia, Papua New Guinea and the Torres Strait. It passes to people only through mosquito bites, not from person to person or through food. Healthdirect notes that since 2022 cases have also appeared in south-eastern mainland Australia, including Victoria.
Serious illness can bring fever, headache, neck stiffness, seizures, confusion and weakness. Anyone with these symptoms needs urgent care; call 000.
Who the Japanese encephalitis vaccine is for
The Australian Immunisation Handbook recommends vaccination for:
- travellers spending 1 month or more in endemic areas outside Australia, including Asia and Papua New Guinea, during the transmission season
- people in an Australian risk region who may be bitten by mosquitoes
- some people whose work involves pigs or mosquitoes, and laboratory workers
Shorter trips can still warrant it when the plans are mainly outdoors in rural areas, such as camping, cycling or working near rice fields and farms. The doctor will look at the season and the regions on your route.
The two vaccines and their doses
Two vaccines are available in Australia, and the choice depends on age, health and timing:
- Imojev is a live vaccine given as a single dose from 9 months of age. Adults do not need a booster.
- JEspect is an inactivated vaccine given as 2 doses 4 weeks apart from 2 months of age. Adults at imminent risk can have an accelerated course with the doses 7 days apart. A booster after 1 to 2 years is advised if the risk continues.
Because Imojev is live, it is not given during pregnancy or to people with a weakened immune system, and women should avoid pregnancy for 28 days after it. JEspect is the usual alternative.
Victorian funding and travel
The Victorian Department of Health provides free vaccine for people aged 2 months or older who live or work in listed high-risk local government areas, and for certain workers such as people at piggeries. That program is about local risk. A vaccine needed only for an overseas trip is generally bought privately.
Mosquito bites: the other half of prevention
No vaccine replaces bite avoidance, which also protects against dengue and malaria. Use a repellent containing DEET or picaridin, wear long, loose clothing, take extra care at dawn and dusk, and sleep in screened rooms or under a net. Smartraveller’s travel health advice covers insect-borne diseases by region.
Cost and booking
For travel, the vaccine itself usually has a cost, and the consultation may too. See the fees page or ask reception. To book online, choose a time and mention the vaccine when you book.
Common questions
I am going to Bali for ten days. Do I need it?
Most short resort stays do not meet the threshold, but rural travel, long outdoor days or repeat trips can change that. A doctor can weigh your itinerary.
Is there a vaccine for dengue or malaria instead?
Malaria has no routine travel vaccine, so bite prevention and sometimes tablets are used. Ask about the travel immunisation consultation for advice covering all of these.
What side effects are common?
Reactions at the injection site and minor general symptoms are common after either vaccine, and they usually pass quickly.
Can I have it with my other travel vaccines?
Often, yes. If you also need rabies vaccine for the same trip, the doctor can plan the visits together.
