What should you know about international yellow fever certificate?

The certificate links your identity to a documented yellow fever vaccination given by an authorised provider. Border authorities may examine it when you arrive from, or travel through, a country with yellow fever transmission risk. Requirements can depend on your itinerary, transit stops and destination rules, which may change.

A certificate is a travel document, not proof that every travel-related infection is prevented. It also does not replace mosquito-bite precautions. Keep the original document safe and make sure names and passport details are consistent.

Check entry and transit requirements early and book a travel appointment if vaccination is advised. Bring your itinerary, passport details, medical history, pregnancy information, allergy history and vaccination records. The clinician can discuss whether yellow fever vaccination is suitable and document it correctly. Carry the certificate while travelling rather than packing it in checked luggage.

Ask for medical advice before travel if you have immune-system problems, a severe allergy history, are pregnant or have another condition that could affect vaccination decisions. After vaccination, seek urgent care for trouble breathing, facial swelling, collapse or rapidly worsening illness. A fever after travel also deserves prompt assessment.

Is vaccination advised for my exact route and transit points? Do my health conditions affect the decision? What should I do if my certificate is lost? Which mosquito precautions should I use?
