WHO has published an updated summary of , including revised statements on the duration of certificate validity.
The age from which travellers are required to provide a certificate of vaccination has changed for several countries and for some destinations certificate requirements have been updated for travellers transiting through yellow fever risk countries.
The period for which a certificate of vaccination against yellow fever is considered valid has changed from 10 years to life-long for a number of countries. However, some countries still require certificates to have been issued within the previous 10 years. Where countries have not communicated their specifications on certificate validity to the WHO, certificates are assumed to be valid for 10 years until further notice.
NaTHNaC currently recommends that all yellow fever certificates be issued with a 10-year expiry date regardless of the destination of the traveller.
These changes are reflected in the intelog country pages online and will appear in the June print edition of intelog.
