World – Yellow fever vaccination booster

20 May 2013 - The recently published SAGE recommendation that a booster dose of yellow fever vaccine every 10 years is not necessary does not change the International Health Regulations (IHR). The provisions for the duration of validity of the yellow fever vaccination certificate under the IHR remain in force as long as state parties have not agreed to change those provisions. WHO will discuss with countries how to best proceed to update those provisions.

Countries, however, have discretion in how they implement the certificate provisions of the IHR and WHO will inform and encourage countries to ensure that their implementation takes account of the latest scientific advice.

Travellers should expect that any change in the implementation by countries to take a few months to be enacted and in the meantime should anticipate that the existing requirements will continue.
