Notice to Readers: Requirements for Use of a New International Certificate of Vaccination or Prophylaxis for Yellow Fever Vaccine

In response to the 2005 revision of the International Health Regulations (IHR 2005), as of December 15, 2007, a new International Certificate of Vaccination or Prophylaxis (ICVP) has replaced the old certificates (1). The new certificate provides space for potential certification of additional types of vaccination or prophylaxis to protect against newly emerging or reemerging diseases or other events of public health importance. However, the only vaccination currently required to be indicated on the ICVP is for yellow fever.

Yellow fever vaccine is required under IHR 2005 by certain countries for entry, and the new ICVP is required for any yellow fever vaccination administered beginning December 15, 2007. Persons vaccinated before that date may use the old certificate until it expires 10 years from the date of vaccination.

The new certificates are available to health-care providers through the U.S. Government Printing Office (GPO). The new ICVPs are available for order from GPO online at, or by telephone (866-512-1800). Additional information regarding the new requirement is available from the CDC Travelers' Health Team by telephone (404-639-4500) or online via the Travelers' Health website at
