Yellow Fever vaccine now life-long, no booster dose required. Following the World Health Assembly’s adoption of an amendment to Annex 7 of the International Health Regulations (IHR), which stipulates that the period of protection afforded by yellow fever vaccination is life-long.
Yellow fever is the only disease specified in the International Health Regulations (2005) (IHR (2005) for which countries may require proof of vaccination from travellers as a condition of entry under certain circumstances and may take certain measures if an arriving traveller is not in possession of such a certificate.
The amendment to Annex 7 of IHR (2005) enters into force and will be legally binding upon all IHR States Parties on 11 July 2016. In the context of international travel, the amendment to Annex 7 changes the period of validity of the related international certificate of vaccination against yellow fever, and the protection provided by vaccination against yellow fever infection under the IHR (2005), from ten (10) years to the life of the person (traveller) vaccinated. Accordingly, as of 11 July 2016, for both existing or new certificates, revaccination or a booster dose of yellow fever vaccine cannot be required of international travellers as a condition of entry into a State Party, regardless of the date their international certificate of vaccination was initially issued. This lifetime validity of these certificates applies automatically to certificates issued after 11 July 2016, as well as certificates already issued.
Note that even if your YF Certificate indicates that it is ‘expired’, you will no longer need a re-vaccination or a booster shot to enter countries that require the YF certificate.
AS THIS DIRECTIVE IS RECENT WE RECOMMEND TRAVELERS TO VERIFY THAT THE COUNTRIES THEY TRAVEL TO AND THOROUGH RECOGNIZE THE ‘WHO’ DIRECTIVE
