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.
