What are the current UK vaccination recommendations for yellow fever for travelers?

UK Vaccination Recommendations for Yellow Fever for Travelers:

• Yellow fever vaccination is recommended from age 9 months onwards and is only available at designated Yellow Fever Vaccination Centres in the UK.
• Vaccination is advised for people aged 9 months or older who are traveling to countries that require an International Certificate of Vaccination or Prophylaxis (ICVP) for entry, or who will be living in yellow fever endemic areas, even if no proof of vaccination is required on entry.
• Infants aged 6–9 months should only be vaccinated if the risk is unavoidable, and expert opinion should be sought; infants under 6 months should not be vaccinated.
• People aged 60 years or older should only be vaccinated if there is a significant and unavoidable risk of yellow fever infection, such as travel to an area with current or periodic transmission risk.
• The vaccine used (Stamaril®) is a live attenuated vaccine given as a single dose, conferring immunity in 95–100% of recipients, with immunity developing at least 10 days after vaccination.
• For most people, a single dose provides lifelong immunity; however, a booster dose after 10 years is recommended for those at persistent risk who were vaccinated under 2 years old, during pregnancy, while immunosuppressed, or before bone marrow transplant.
• Yellow fever vaccination should not be given to people with a history of anaphylaxis to the vaccine or its components, egg allergy, thymus disorders, immunocompromised individuals, or pregnant women unless travel is unavoidable and risks are assessed individually.
• Travelers unable to receive the vaccine should be informed of the risk and advised on strict mosquito bite avoidance measures.

Note: The ICVP becomes valid 10 days after vaccination and remains valid for life.

Travelers are also advised to use standard mosquito bite precautions as yellow fever is transmitted by Aedes mosquitoes.
