Yellow fever vaccination during pregnancy

Yellow fever vaccine is live attenuated. Pregnancy is therefore an important part of the clinical discussion, alongside the likelihood of exposure on your itinerary and any country requirement for a certificate. A clinician may advise changing travel plans, considering documentation options, or vaccination when the travel-related risk makes that the more suitable course.

Do not rely on a general online rule for this decision, because the destination, timing, medical history, and route all affect the advice.

Contact an obstetric clinician or travel-health service as soon as travel is being considered. Share your expected dates, every destination and transit stop, previous vaccinations, allergies, medicines, and any immune-system condition. Check official entry requirements separately from medical advice, since a certificate rule and a health recommendation are not the same thing.

If you receive a certificate or other travel document, store it where it is easy to show with your passport.

Seek prompt advice if you are pregnant and travel to a yellow-fever-risk area is unavoidable, or if departure is near. After any vaccination, get urgent help for breathing problems, facial swelling, fainting, or a severe or rapidly progressing reaction.

Ask how your planned route changes the balance of risks, whether postponing or altering travel is practical, and what mosquito-bite precautions suit your trip. Ask which documents may be needed at the border if vaccination is deferred.
