Yellow fever and polio vaccination

Yellow fever is a mosquito-borne viral illness in particular parts of the world. Polio is a viral infection spread through contamination from stool, and vaccination status can matter for travel to or from areas with poliovirus circulation. Requirements and recommendations may be different for each infection.

A travel clinician considers where you will stay, the places you transit through, the length and purpose of the trip, and your existing immunisation history. An adult who completed childhood polio vaccination may still need an individual review for travel.

Schedule a travel-health appointment with enough time to organise any recommended doses and certificates. Bring your vaccine booklet or digital record, details of previous yellow fever vaccination, and your itinerary. Share allergies, immune-system conditions, current medicines, pregnancy or breastfeeding.

Hand hygiene and safe food and water habits remain useful during travel, alongside vaccination. Mosquito precautions are also needed where yellow fever is a concern because vaccination does not prevent other mosquito-borne infections.

Emergency assessment is appropriate for symptoms of a severe allergic reaction after a vaccine, including wheeze, facial swelling, widespread hives or fainting. Seek urgent care during or after travel for fever with jaundice, severe headache, confusion, weakness, neck stiffness, or persistent vomiting.

Ask whether you need a polio booster or travel certificate, whether yellow fever vaccination is appropriate, and how the plan fits your departure date. Ask which vaccine reactions are expected and which need urgent review.
