In short. There are no mandatory vaccinations for entry to Bali. Indonesia's only requirement on the WHO list is a yellow fever vaccination certificate for travellers aged nine months and over who arrive from countries with a risk of that disease; it is not needed from Europe. Recommended: hepatitis A, hepatitis B, typhoid, routine vaccinations including measles, and Japanese encephalitis for those who live on the island for a month or longer. A rabies vaccine before the trip is optional; after a bite the vaccine is given on the spot. There is no malaria in Bali, Ubud or the Gilis, and tablets are needed only for eastern Indonesia and Komodo. For dengue and chikungunya, nets, repellent and clothing protect you; a dengue vaccine is registered in Indonesia, a course of two doses. Start four to six weeks before departure.
What is required at entry. Under the WHO list of yellow fever requirements, Indonesia requires an international vaccination certificate only from people older than nine months who arrive from a country with a risk of yellow fever transmission; Indonesia itself is not on the list of risk countries. These are countries of Africa and South America, and the requirement does not apply to arrivals from Europe. No other vaccinations are checked at the border, and COVID-19 certificates have not been asked for since 2023. What is actually checked on arrival is in the step-by-step arrival guide.
What is recommended. The CDC list for Indonesia:
- Routine vaccinations: diphtheria, tetanus, whooping cough, polio, measles, rubella, mumps, chickenpox, flu. CDC separately asks all travellers to be fully vaccinated against measles: there are outbreaks around the world, and children aged 6 to 11 months get an early dose.
- Hepatitis A: for everyone not yet vaccinated, from one year of age. It is spread through food and water and is the main "tourist" infection. Get the vaccine two to four weeks before departure.
- Hepatitis B: for everyone not yet vaccinated, of any age. It is spread through blood: clinics, tattoos, scooter injuries.
- Typhoid: for most travellers, especially those who eat at warungs and markets. The vaccine does not give full protection, so the rules on food and water still apply.
- Japanese encephalitis: for those who move here, live on the island for a month or longer, or often travel to rural areas; for a short trip around the resorts CDC does not recommend it.
- Rabies before the trip: CDC advises discussing it with a doctor if you plan to work with animals, go hiking or live far from clinics. Bali has many dogs with rabies, but the vaccine after a bite is available free in state clinics; the procedure is in the rabies guide. A course before the trip makes treatment after a bite simpler, but does not replace it.
- Chikungunya: in 2026 CDC notes an increased risk in Indonesia and allows vaccination for stays of six months or longer.
There is no malaria in Bali. According to CDC data of 23 April 2025, there is no malaria transmission in the resort areas of Bali, in Ubud, on the Gili islands or in Jakarta. Prevention with tablets is needed in eastern Indonesia: Maluku, East Nusa Tenggara including Labuan Bajo and Komodo, Papua, and rural areas of Kalimantan, Lombok, Sulawesi and Sumatra. If you are going only to Bali, Nusa Penida and the Gilis, you do not need malaria tablets; if you are going further, the drug and the schedule are prescribed by a doctor before you leave, and self-treatment is dangerous here. For where to go from the island, see the Gili islands guide.
Dengue, chikungunya, Zika. Three viruses carried by daytime Aedes mosquitoes, and for two of the three there is no vaccine for a tourist. Dengue is present in Bali all year, with a peak in the rainy season: symptoms, when to go to hospital and why you must not take ibuprofen are in the dengue guide. The Qdenga dengue vaccine was registered by BPOM in Indonesia on 19 August 2022 for ages 6 to 45, two doses three months apart; it is given in private clinics on the island, it is not part of the free vaccination programme. In August 2026 CDC issued a notice on cases of Zika in people returning from Bali: pregnant women and those planning a pregnancy should discuss the trip with a doctor, and everyone else should protect themselves from bites and use protection during sexual contact during and after the trip. Repellent with DEET or icaridin, long sleeves at dawn and dusk, screens on the windows and air conditioning do more than any vaccine.
Leptospirosis and other things. After floods and downpours leptospirosis rises in Indonesia: an infection from water that rats have been in. Do not walk barefoot through puddles and floodwater, and cover cuts; symptoms and treatment are in the leptospirosis guide. Sun, food poisoning and bites are not about vaccines, but they are what most often send tourists to a clinic: first-aid kit, food poisoning and diarrhoea, snakes and animals.
When to start. Start four to six weeks before departure: hepatitis A needs two weeks to build protection, a rabies course needs two to three weeks, and Japanese encephalitis needs two doses four weeks apart. Check in advance that the typhoid and Japanese encephalitis vaccines are available, because they are not stocked everywhere. If you leave in a week, get what protects with one dose, hepatitis A first, and the rest in Bali: private clinics on the island vaccinate adults and children, and the list of clinics is in the hospitals guide.
Children. The routine schedule for their age, hepatitis A from one year, measles from six months when travelling, Japanese encephalitis from two months if the child will live on the island. Carry a vaccination certificate in English: it is asked for in kindergartens and schools in Bali, as described in the schools guide.
Our advice. Check tetanus and measles in your certificate, get hepatitis A and B and typhoid if you are going for more than two weeks or plan to live here. Japanese encephalitis and rabies in advance for those who move with children or will travel a lot through villages. And buy insurance that covers dengue and hospitalisation, there is a separate guide: it will be useful more often than any vaccine.
What this means for you. At the border you will not be asked about anything except yellow fever, and only when arriving from Africa or South America. Hepatitis, typhoid and routine vaccinations are your job a month before departure; there is no malaria in Bali, repellent and a net protect against dengue, and after a dog bite the vaccine is given on the spot the same day.
