A Yellow Fever vaccination certificate is only required for travellers arriving by air or sea, from or in transit through, a country with risk of Yellow Fever transmission 6 days prior to arrival.* 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.
Children: A vaccination certificate is required for children over 6 months of age. However, Yellow Fever vaccination is not recommended for children under 9 months of age. If travel is unavoidable and the child's physician considers vaccination unwise, ask for a letter on the physician's own stationary explaining the reason for not vaccinating the child. Note that some countries may not honour this and the infant may be refused entry or be put under surveillance upon arrival.
* ADDITIONAL REQUIREMENT: A vaccination certificate is also required for travellers arriving from Rwanda. In addition, all travellers who do not have proof of vaccination will be quarantined for up to 6 days.
Alert: 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.

Validity of certificate
A Yellow Fever certificate is valid 10 days after vaccination.
The World Health Organization announced that as of 11 July 2016, existing and new Yellow Fever vaccination certificates are valid for life. 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.
Note: 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.
