Timing
At least 10 days before travel, which is when the vaccination certificate becomes valid. Booking several weeks ahead is wise because appointments at designated centres can fill up.
Typical course
A single injection. For most people one dose gives long-lasting protection, and the international certificate issued afterwards does not need renewing.
Often relevant for
- Sub-Saharan Africa
- Brazil and other parts of South America
- Panama and parts of Central America
- Countries requiring a certificate on arrival
Yellow fever is spread by infected mosquitoes. Many people have a mild illness, but a minority develop a severe form with fever, jaundice and bleeding that can be life-threatening, and there is no specific treatment for the virus itself.
It is different from most other travel vaccines in one important way: in the UK, yellow fever vaccine can only be given by registered Yellow Fever Vaccination Centres. Not every pharmacy or travel clinic can offer it, so check that a clinic is a registered centre before you book.
Some countries ask for a valid yellow fever certificate when you arrive, particularly if you are coming from, or have passed through, a country with a risk of the disease. Check the entry rules for your whole route, including stopovers.
The vaccine is not suitable for everyone. Age, certain medical conditions, some medicines and past reactions can all affect whether it is recommended, so a clinician will assess your history before giving it.
Not sure if you need this one?
A travel health consultation looks at your whole itinerary, not just one vaccine.
