Bali & Indonesia Travel Vaccines: What Visitors Should Check Before Travelling

If you are travelling to Bali or elsewhere in Indonesia, the health precautions that may be relevant depend on your exact itinerary rather than the country name alone. A short hotel-based stay in Bali can involve different considerations from island-hopping, rural travel, volunteering, trekking or spending time in Papua. Before you travel, check your route, travel dates, previous vaccinations and planned activities against current TravelHealthPro guidance for Indonesia.

This guide is for general travel-health planning. It does not replace an individual clinical assessment, and recommendations can change when official guidance, outbreaks or entry rules change.

Why Bali and wider Indonesia should not be treated as one risk area

Indonesia is a very large archipelago, and health risks are not identical across every island or region. Malaria risk, mosquito exposure, access to healthcare and the type of activities you plan can all vary considerably. A traveller staying in a well-developed part of Bali may have a different risk profile from someone visiting remote islands, rural areas or Papua.

That is why a useful travel-health assessment should include the islands and regions you will actually visit, your overnight stops, how long you will stay, the type of accommodation and any outdoor or animal-related activities.

When should you arrange travel-health advice?

Where possible, the NHS recommends seeking travel-health advice at least 4 to 6 weeks before departure. This allows time to review routine vaccinations, discuss any destination-specific vaccines and complete multi-dose schedules where needed.

If you are travelling sooner, it can still be worth asking for advice. Some vaccines and other travel-health measures may still be appropriate, but you may not have time to complete every recommended course or develop full protection before departure. For more detail, read When Should You Get Travel Vaccinations Before Travelling?.

Start by checking your routine UK vaccinations

Before focusing on destination-specific vaccines, check whether your routine UK vaccinations are up to date. Depending on age and vaccination history, this can include protection against infections such as measles, mumps and rubella, and ensuring appropriate tetanus-containing vaccination has been completed.

If you do not know what vaccinations you have had, check the NHS App where available or ask your GP practice for your vaccination record. Bring whatever information you can find to any travel-health appointment.

Which vaccines may be considered for Bali and Indonesia?

There is no single vaccine list that applies to every visitor. Current official recommendations vary according to previous vaccination, itinerary, length of stay, activities and personal risk. For a broader explanation of how travel vaccines are selected, see What Vaccines Do You Need for Travel?.

Hepatitis A

TravelHealthPro recommends hepatitis A vaccination for previously unvaccinated travellers to Indonesia. The infection can spread through contaminated food or water, so vaccination should be combined with sensible food, water and hand-hygiene precautions.

Typhoid

Typhoid vaccination is recommended for most travellers to Indonesia, with particular importance for people who may have greater exposure to uncertain food or water hygiene, longer stays or frequent travel. Vaccination does not replace careful food and water precautions.

Tetanus and routine protection

Travellers should have completed the UK tetanus vaccination course. A booster may be advised in some circumstances, particularly where medical facilities may be limited and the last tetanus-containing dose was given more than ten years ago.

Hepatitis B

Hepatitis B vaccination may be considered for travellers and is particularly relevant where there may be exposure to blood or body fluids, medical or dental treatment, tattoos or piercings, sexual contact, contact sports, longer stays or travel to visit friends and relatives.

Rabies

Rabies is a risk in Indonesia. Pre-exposure vaccination is particularly relevant for some travellers whose activities, length of stay or destination increase the chance of animal exposure or make prompt access to post-exposure care more difficult. Even after pre-exposure vaccination, urgent medical assessment is still required after a possible exposure.

Japanese encephalitis

Japanese encephalitis occurs in Indonesia, with risk influenced by where you stay, how long you remain and the type of activities you undertake. Vaccination may be considered for longer stays, frequent travel, uncertain itineraries or shorter trips involving higher-risk rural exposure such as time around rice fields, wetlands or pig-farming areas.

Do you need malaria tablets for Bali?

For most standard Bali itineraries, current UK malaria guidance classifies Bali as a low-risk area. The usual focus is awareness of malaria risk and consistent mosquito-bite prevention rather than routine antimalarial tablets for every traveller. Antimalarial medication can still be considered for some people at higher risk of malaria or severe complications after an individual assessment.

Do not assume the same advice applies to every part of Indonesia. Current guidance identifies high malaria risk in Papua, low risk in Bali, Lombok, Java and Sumatra, and no malaria risk in Jakarta. If your trip includes several islands, remote regions or overnight stays away from Bali, the exact route matters.

Mosquito-bite prevention matters throughout Indonesia

Mosquito-borne illnesses in Indonesia include dengue, chikungunya, Japanese encephalitis, Zika and malaria in risk areas. Because different mosquitoes bite at different times of day, protection should not be limited to night-time.

• Use an effective insect repellent on exposed skin and reapply it according to the product instructions.
• Wear loose-fitting clothing that covers the arms and legs where practical.
• Choose screened or air-conditioned accommodation where possible.
• Use a mosquito net if sleeping accommodation is not adequately screened.
• Continue bite-prevention measures during the daytime as well as from dusk to dawn.

Zika and pregnancy planning

TravelHealthPro lists a risk of Zika virus in Indonesia. Pregnant travellers should discuss the suitability of travel and the possible risks with an appropriate healthcare professional. Couples planning pregnancy should check the latest Zika guidance before travel because advice about avoiding conception depends on which partner travelled and when the last possible exposure occurred.

Because Zika guidance can change as surveillance information develops, use the current TravelHealthPro Indonesia page rather than relying on an old checklist or social-media post.

Food and water precautions

Food and water precautions remain important because infections such as hepatitis A, typhoid and travellers’ diarrhoea can be spread through contaminated food or water. Current GOV.UK health advice for Indonesia states that tap water is not safe to drink.

• Choose food that is freshly prepared, thoroughly cooked and served hot.
• Be cautious with raw or undercooked meat, fish, shellfish and eggs where hygiene is uncertain.
• Use sealed bottled, boiled or otherwise safe water for drinking where appropriate.
• Avoid ice when you cannot be confident it was made with safe water.
• Wash your hands before eating and after using the toilet.

Animal bites and rabies: take particular care in Bali

Dogs and monkeys are common in parts of Bali, including around temples and tourist areas. Avoid touching or feeding dogs, monkeys and other mammals. Children should be supervised closely around animals because bites and scratches may be small or go unreported.

If you are bitten, scratched or licked on broken skin, wash the area thoroughly and seek urgent medical assessment. This is still necessary if you received rabies vaccination before travel because post-exposure care may still be required.

Do you need a yellow fever certificate?

Indonesia itself does not have a yellow fever transmission risk, but proof of yellow fever vaccination can be required for travellers aged 9 months or over arriving from a country with a risk of yellow fever transmission. Your full journey matters, including countries visited before Indonesia and relevant transit arrangements.

Check the latest Indonesia entry requirements on GOV.UK shortly before travel because requirements can change. If yellow fever vaccination or certification is required, it must be arranged through a designated Yellow Fever Vaccination Centre.

Long-term conditions, medicines and travel insurance

If you have a long-term medical condition, are pregnant, take regular medicines or have a weakened immune system, plan ahead. The suitability and timing of some vaccines or medicines can depend on your health history, age, pregnancy status and current treatment.

Make sure your travel insurance covers the places you are visiting and the activities you plan to do. Medical care can be expensive, and access to higher-level care may be limited in remote parts of Indonesia. If you need regular prescription medicines, check the rules for carrying them and take enough for your journey where appropriate.

Check current entry and local safety information before departure

Entry requirements and local safety information can change independently of vaccine guidance. GOV.UK currently advises travellers to complete the All Indonesia customs and health declaration within 72 hours of arrival and provides information about the Bali tourist levy, visas and other entry requirements.

Indonesia is also volcanically active. If your plans include trekking, island travel or areas near volcanoes, check current local restrictions and the latest FCDO travel advice before and during your trip. Make sure any planned activities remain covered by your travel insurance.

Frequently asked questions

What vaccines should I check before travelling to Bali or Indonesia?

Start by checking that routine UK vaccinations are up to date. Current TravelHealthPro guidance recommends hepatitis A for previously unvaccinated travellers and typhoid for most travellers. Other vaccines, including hepatitis B, rabies and Japanese encephalitis, may be considered depending on itinerary, length of stay, activities and individual circumstances.

Does vaccine advice differ between Bali and other parts of Indonesia?

Yes. The exact islands, regions and activities can change the risk assessment. A standard Bali holiday may have different malaria and exposure considerations from travel to Papua, remote islands, rural areas or longer multi-island trips.

Do I need malaria tablets for Bali?

Not routinely for every traveller. Bali is currently classed as a low-risk malaria area, where awareness and mosquito-bite avoidance are central. Antimalarials may be considered for some higher-risk travellers after an individual assessment. Other parts of Indonesia can have different malaria risk.

What should I do after a dog or monkey bite in Bali?

Wash the wound thoroughly and seek urgent medical assessment as soon as possible. Do this even if the wound appears small and even if you had rabies vaccination before travelling.

How early should I arrange travel-health advice?

Aim for at least 4 to 6 weeks before departure where possible. If you are travelling sooner, advice can still be useful, but some vaccine courses may not be completed before you leave.
