What should you know about airport yellow fever vaccination?

Yellow fever is an infection spread by mosquitoes in certain tropical regions. The vaccine trains the immune system to recognise the virus before exposure. Because travel rules depend on the countries visited, transit stops, and current entry requirements, a vaccination may be relevant even when your departure airport does not ask for it. A health professional can check whether a certificate is needed for your itinerary and explain how the certificate is issued.

The vaccine is live attenuated, meaning it uses a weakened form of the virus rather than the disease-causing form. Tell the clinician about pregnancy, immune-system conditions, medicines that suppress immunity, severe allergies, and previous vaccine reactions before vaccination.

Arrange a travel-health appointment well before departure so there is time to review your route, medical history, and other recommended travel measures. Take your passport or travel documents if your service records vaccination details there, and keep the certificate with your travel papers. Continue using mosquito protection, such as long sleeves, repellent, and screened or air-conditioned accommodation; vaccination does not prevent every mosquito-borne illness.

After vaccination, mild soreness, tiredness, or a low fever can occur. Rest, drink fluids, and follow the advice given by the vaccinator. Do not share the vaccine with another traveller or assume that a previous dose is suitable for every new itinerary without checking current advice.

Seek urgent medical help for trouble breathing, swelling of the face or throat, widespread hives, collapse, confusion, a seizure, or rapidly worsening illness after vaccination. These can signal a serious reaction. Contact a clinician promptly for a persistent high fever, severe weakness, yellowing of the skin or eyes, or symptoms that concern you during or after travel. For itinerary-specific advice, discuss Yellow Fever Vaccination with a qualified travel-health professional.

Ask whether your destination or transit route requires a certificate, whether your medical conditions or medicines affect eligibility, and what mosquito precautions or other vaccines belong in your travel plan.
