Following administration of YF vaccine, when does the certificate become valid?

A. Where a person is receiving the vaccine for the first time, the certificate becomes valid 10 days after the vaccine is given. See the illustration below. If re-vaccination occurs within 10 years of a previous vaccine and a Port 37 certificate (or other official certificate documenting YF vaccination) is in the traveller’s possession, the new certificate is valid immediately. If the traveller is due to depart within 10 days of re-vaccination, it is suggested that either details of the previous YF vaccination are entered on the new certificate, OR the traveller carries their original Port 37 in addition to their new certificate.
