What should you know about yellow fever vaccine during pregnancy?

The clinician weighs the potential risk of yellow fever exposure during the trip against the considerations of giving this vaccine in pregnancy. That balance is different for someone travelling to an area where exposure is possible than for someone whose only concern is an administrative entry requirement.

Your stage of pregnancy, medical history, previous vaccine reactions, other medicines, and the feasibility of changing or postponing travel can all matter. A certificate requirement does not automatically mean vaccination is the appropriate choice for every pregnant traveller.

Contact an experienced travel-health clinician and your maternity care team before making arrangements. Bring your due-date information, immunisation history, allergy history, medication list, and a full itinerary that includes transit airports. Ask about destination-specific mosquito avoidance as well as documentation requirements.

If vaccination is recommended, make sure the travel document is completed accurately and keep it with your passport. If it is not recommended, ask the clinician what supporting documentation may be appropriate and whether your travel plans should be reconsidered.

Seek urgent medical help after vaccination for breathing trouble, swelling of the lips, face, or throat, severe hives, collapse, or a rapidly worsening illness. During travel, get prompt assessment for fever or feeling seriously unwell, particularly after mosquito exposure in a place where yellow fever can occur.

Ask how your destination, season, activities, and transit points affect the decision. Ask about mosquito-bite prevention, certificate rules, and what symptoms during or after the trip should prompt urgent care.
