Do I need vaccinations to visit Brazil?

The Centers for Disease Control and Prevention recommend that all travellers are up-to-date with their routine vaccinations including measles, mumps, rubella, diphtheria, tetanus, pertussis (whooping cough), polio, chicken pox and influenza. These vaccinations are given as part of the National Immunisation Program (NIP). For a full list please refer to the NIP schedule, available here. In some cases, you may need a booster or re-vaccination against a disease to ensure you still have immunity. 

Travellers to Brazil who are aged 5 years or older should also ensure they are fully vaccinated against COVID-19.

Some diseases that are not common in Australia, are present in Brazil, such as typhoid and hepatitis A. Vaccinations against these diseases are recommended. In addition, depending on where you are going in Brazil and what activities you are undertaking, vaccinations against hepatitis B and yellow fever, and preventative medication for malaria may also be required. If you have travelled to Brazil, you may be asked to present a valid yellow fever vaccination certificate by border control when you come back into Australia.

How can cholera be prevented?

Although vaccines for cholera are available, routine vaccination is generally not recommended for cholera and is not an official entry requirement for any country. Vaccination may be considered for special cases, such as people with some existing medical conditions, or those working in humanitarian relief or natural disaster areas. 

Before and during travel to high-risk countries: 7

  • seek advice from a travel medical clinic or an experienced general practitioner on how to protect yourself from cholera and other diarrhoeal illnesses
  • regularly wash hands with soap and water
  • drink only water that has been boiled or disinfected with iodine or chlorine tablets. Carbonated bottled drinks are usually safe (if no ice is added)
  • eat freshly prepared and/or hot food, and avoid eating raw foods or vegetables (unless they can be peeled) 
  • always practice good food handling procedures.
