Yellow Fever (YF) is a life-threatening disease caused by infected Aedes aegypti, a mosquito species that breeds in the proximity of human habitation. It’s a mosquito-borne viral disease. Yellow Fever is of great magnitude due to its high-mortality rate. Mild symptoms include nausea, vomiting, fever, headache, abdominal and muscle discomforts. Severe symptoms include jaundice, liver, kidney, and respiratory failure. The virus doesn’t spread through contact but the symptoms if not taken care of at the right moment, might even lead to death.

Countries that are prone

Yellow Fever prevails in countries like South America, Panama, Trinidad and Tobago. The disease is endemic and predominates on a large-scale in sub-Saharan Africa.


The YF 17D vaccine strain is developed from a wild-type YF virus (the Asibi strain) isolated in Ghana in 1927. It is attenuated by consecutive serial passages in chicken embryo and dual sub-strains of the 17D vaccine virus are widely used for vaccine production. The final vaccine prep is then lyophilised in cold-chain conditions for further use.

Yellow Fever Vaccine (YFV) is by far a safe and an effective vaccine. Also this 17D vaccine is given only at authorised centres. Our Yellow Fever Vaccination Clinic at Haddenham is an authorised travel clinic for this vaccine. The YF vaccine is given as a single subcutaneous or intramuscular injection. Once you get a jab of this vaccine, you are provided with an International Certificate of Vaccination or Prophylaxis (ICVP). This certificate is valid for up to 10 years from the 10th day of your vaccination. If you remain at risk of this disease, booster shots may be required.
