Preventing yellow fever
There are several methods to prevent YF: mosquito control and bite avoidance, and vaccination.
A highly effective live, attenuated (weakened) YF vaccine has been available for more than 70 years. Vaccination is recommended for persons at risk of yellow fever infection. The contraindications and precautions (see below) for this vaccine should be considered according to individual risk assessment. Persons aged 60 years or older should only be given the vaccine when there is significant and unavoidable risk of acquiring YF infection, such as travel to an area where there is current or periodic risk of YF transmission (see Aged 60 years or older section below).
Persons who travel to YF risk countries, or areas within countries with risk of transmission, without the benefit of vaccination should be advised of the risk of contracting YF. Meticulous mosquito bite avoidance measures are advised for all travellers.
- Yellow fever (YF) is a viral disease transmitted by mosquitoes causing a spectrum of disease from mild to severe symptoms.
- Mosquito bite avoidance and yellow fever vaccination is recommended for travellers visiting countries where there is a risk of YF virus transmission.
- Under the International Health Regulations (2005), an International Certificate of Vaccination or Prophylaxis for YF may be an entry requirement for some travellers to YF risk countries.
- YF certificate requirements are not necessarily connected to the risk of disease for a traveller.
- The YF vaccine is only available at designated UK Yellow Fever Vaccination Centres (YFVCs). We are a designated Yellow Fever centre.
- There is no treatment for YF disease. Care of an infected person is based on managing the symptoms.
