For your protection, vaccination is recommended for all travellers 9 months of age and older.
Due to the current outbreak in the states of Distrito Federal, Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo, travellers who were vaccinated more than 10 years ago should consider an additional dose of Yellow Fever vaccine as a precaution. A single dose of Yellow Fever vaccine provides adequate protection for most travellers and under World Health Organization guidelines, countries cannot require travellers to receive a booster dose as a condition for entry. However, travellers going to or temporarily residing in areas with recently confirmed cases may be at increased risk if 10 years have lapsed since their last Yellow Fever vaccination. As such, a one-time booster dose is recommended.
Travellers going to areas with recently confirmed cases (see above) and who have been advised against the Yellow Fever vaccine due to medical reasons should postpone travel to these areas. Meticulous anti-mosquito bite measures are essential for travel to other areas at risk of Yellow Fever transmission.
Note: Areas not considered currently at risk of Yellow Fever transmission include Alagoas, Ceará, Rio Grande do Norte, Paraiba, Pernambuco, and Sergipe.

Countries may change their vaccination requirements without notice and in some instances border agents use their discretion to deny entry despite the officially stated requirements.
If there is risk of Yellow Fever at your destination, whether vaccination is required for entry or not, be prepared to show a certificate of vaccination or a waiver stating the medical reasons for not being vaccinated.
