A Yellow Fever vaccination certificate is required for travellers 1 year of age and older coming from - or who are in airport transit for more than 12 hours in - Brazil, the Democratic Republic of the Congo, and Uganda.
The vaccination requirement is imposed by this country for protection against Yellow Fever since the principal mosquito vector Aedes aegypti is present in its territory.

For your protection, Yellow Fever vaccination is recommended for all travellers 9 months of age and older travelling at altitudes below 2300 m / 7546 ft in Esmeraldas and the Amazonian provinces of Orellana, Morona-Santiago, Napo, Pastaza, Sucumbios, and Zamora-Chinchipe.
Note: Vaccination is not recommended for the rest of the country. Take meticulous anti-mosquito bite measures during the daytime at altitudes below 2300 m / 7546 ft. Quito, Guayaquil, and the Galápagos Islands are risk free.
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.
A Yellow Fever certificate is valid 10 days after vaccination.
Existing and new Yellow Fever vaccination certificates are now valid for life. The World Health Organization announced that as of 11 July 2016, countries can no longer require travellers to show proof of re-vaccination or a booster dose as a condition of entry. Travellers should note that this new regulation may not be honoured by all border authorities during the transition phase.
Vaccination waiver: A vaccination waiver can be issued by your medical practitioner if the Yellow Fever vaccine is contraindicated for medical reasons. Be aware that problems may arise when crossing borders and the vaccination waiver may not be honoured. Take meticulous anti-mosquito bite measures during the daytime in Yellow Fever risk areas.
