Yellow fever and flu vaccine together: what to know

Yellow fever vaccination is used for people travelling to locations where exposure or entry rules make it relevant. Flu vaccination has a different purpose, helping protect against seasonal influenza. A travel clinician considers both needs alongside the time before departure, your vaccination history, and any health factors that could affect the recommendation.

Your previous reactions to vaccines, immune-system health, pregnancy or breastfeeding, allergies, current medicines, and recent illness are all relevant. Bring any vaccination records you have, including details of a reaction if one occurred. This helps the clinic make a safe, tailored plan rather than relying on memory alone.

Book with an authorised travel vaccination clinic promptly if departure is near. Take your full itinerary, including stopovers, and your routine immunisation record. Tell the clinician if you currently have a fever or feel acutely unwell, because they may advise on the right timing for vaccination.

After vaccination, follow the clinic's instructions about expected local soreness, feverish feelings, activity, and when to seek advice. Keep any travel documentation in an accessible place with your passport, and check destination entry rules again if your route changes.

Seek urgent care for trouble breathing, swelling of the face or throat, widespread hives, collapse, or severe weakness after any vaccination. Contact the clinic promptly for symptoms that are severe, worsening, or unexpected after your appointment. During or after travel, urgent assessment is needed for fever with severe headache, repeated vomiting, confusion, bleeding, or yellowing of the skin or eyes.

Ask whether both vaccines are appropriate at the same appointment, whether any of your medicines or conditions change the plan, and how the timing relates to your departure and destination requirements. Ask what reactions are expected, what documentation to retain, and which mosquito precautions are suitable for your itinerary.
