CDC 731. Formerly PHS-731. International Certificate of Vaccination or Prophylaxis as Approved by the World Health Organization = Certificat International de Vaccination ou de Prophylaxie Approuve par L'Organisation Mondiale de la Sante. Note that this is the American version of the WHO-ICV issued by U.S. Department of Health and Human Services.
Known popularly as the Carte Jaune or Yellow Card, this is the international certificate of vaccination (ICV) as approved by the World Health Organization. The Yellow Card is recognized internationally and may be required for entry to certain countries where there are increased health risks for travelers.
Before departing for a foreign destination, a traveler must visit a healthcare provider and receive the required vaccinations, which the doctor must list on the form per the instructions and sign and date. The Yellow Card must then be kept with the traveler's passport as he or she travels, since it serves as a medical "passport" of sorts as proof of vaccination, including booster shots.
Primary audience are travelers (and medical centers distributing the Yellow Card to patients) who need to go to certain countries where this document is required to prove healthiness and that the recipient has received proper vaccinations, and organizations in need of providing this document.
