Yellow fever is a viral illness which is most commonly spread into the blood stream by mosquitos and is most commonly found in parts of sub-Saharan Africa & South America. The virus which causes the disease is one of a group of viruses known as arboviruses (arthropod borne viruses). Arbovirus illnesses have two phases.
The illness can cause fever, headaches, abdominal pain and vomiting and damage to the blood vessels and signs of liver and kidney failure. Liver failure is associated with jaundice hence the name "yellow fever". Many yellow fever infections go unrecognised and those who do recover do so completely and are immune thereafter. However, severe and life threatening illness is not uncommon and Overall about 5% of Yellow Fever patients die
There is currently no cure for yellow fever but fortunately it is one of the few arboviruses where vaccination is available.
All travellers going to endemic areas will require a yellow fever vaccination certificate and travellers going to some parts of Asia will also require a certificate. This certificate is mandatory for entry into certain countries; in particular East Africa. It is recommended that the traveller carries the certificate along with his or her passport when travelling to and from countries.
The yellow fever vaccination can only be given at designated and registered centres. The Independent General Practice is a registered yellow fever centre and will issue you with your international certificate of vaccination.
You will need to have the yellow fever vaccine a minimum of 10 days before you are due to travel. This is because your certificate is only valid 10 days after your vaccination and then remains valid for 10 years. Although they maybe able to travel to the country, assuming that they are not stopping at any point in a country that although requires a Yellow fever certificate.
If you cannot be vaccinated against yellow fever for medical reasons (or for infants aged under nine months), your GP may be able to issue you with a medical waiver letter. This will explain why you are unable to have the vaccine. The letter should be written on headed notepaper, including the practice details. It may be accepted by some immigration authorities.
If you lose your certificate, you may be able to get another one re-issued as long as you have details of the vaccination batch number and the date that you had the vaccination.
If you're travelling from an area where there's a risk of yellow fever without a valid yellow fever certificate, immigration officials are legally entitled to quarantine travellers for a period of at least seven days at the point of arrival into a country.
Anyone aged 9 months or older can be given a single dose of the vaccine, which will provide protection against yellow fever for 10 years. After this time, a booster dose will be required.
Children aged 6-9 should only be vaccinated against yellow fever if the risk of developing the condition during travel is unavoidable. The yellow fever vaccine is not suitable for children£under 6 months old.
After having the yellow fever vaccine, 10-30% of people will have mild side effects, such as headache, muscle pain, soreness at the injection site & mild fever. However, details of possible side effects and special precautions should be discussed during the appointment.
Please be aware that for full immunity some vaccination courses, with more than one vaccine required, may take up to a month or longer. Please, also be aware that many vaccinations will not become fully effective until weeks after the course completion. It is strongly advised that you leave plenty of time to complete the course before your trip. Intervals between different vaccines or doses are recommended, which allows time for antibodies to be produced and any reaction to the vaccine to subside.
The above information should only be used as a guide and is not a substitute for medical advice. All vaccinations are only carried out following a Travel Risk Assessment and Consultation. The brand of vaccine we supply may also vary depending on the current supply status of a particular vaccine.
