To enter Indonesia, there are no particular vaccination requirements. When choosing whether or not to take preventative measures and get vaccinated against diseases that are common in Indonesia and the neighboring South East Asian nations, there are a number of possible health hazards to take into account.
Your specific circumstances, which should be evaluated with a medical practitioner, will have a significant impact on the immunizations you require for Bali. This is merely basic information and should not be used in place of speaking with a Travel Vaccination Clinic physician.
Both hepatitis A and hepatitis B can be prevented by vaccination, and if you're originally from Australia, hepatitis B is now covered in the childhood immunization schedule. The doctor can verify that you are up to date if you are unclear if you have had vaccinations against any or both of them.
Typhoid fever is another water- and food-borne illness common in areas with poor sanitation. Travelers staying in rural areas or planning to visit local markets should consider this vaccine. Although there is no malaria vaccine, antimalarial medication may be recommended for travelers visiting specific regions of Indonesia, especially rural areas or places where the disease is more common.
