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.
