Yellow Fever is spread by mosquitoes and is found in tropical parts of Africa and South America. Some countries require proof of yellow fever vaccination in the form of an International Certificate of Vaccination before they allow a traveller to enter. Failure to provide a valid certificate can lead to a traveller being quarantined, immunised or denied entry.
A LIVE attenuated (weakened) strain of Yellow Fever virus.
Persons aged nine months or older who are travelling to countries that require an International Certificate of Vaccination for entry, or who are travelling to or living in infected areas or countries in the yellow fever endemic zone even if these countries do not require evidence of immunisation on entry. Additional vaccine information: Only a licenced Yellow Fever Centre can provide vaccination. Travellers will require an Internarional Certificate of Vaccination prior to travel to countries where the disease is found. The certificate only becomes valid 10 days after injection. Travellers should factor this in to their plans.

General issues: There is a risk of a rare but serious adverse event, whcih particularly affects infants and older patients. Vaccination should only be provided after a careful assessment of health and travel plans by the clinic. Specific issues: HIV infected patients should not be vaccinated. Patients with thymus disease should not be vaccinated. Those who have received a live vaccination within the last 4 weeks eg MMR or BCG should delay Yellow Fever vaccination by one month. However live vaccines can be given together on the same day.
The vaccine may not be given to pregnant women. In breast feeding, there is no evidence of harm to the baby, but the need for vaccination requires careful assessment.
Adverse reactions following yellow fever vaccine are typically mild and consist of headache, muscle pain, low grade fever and/or soreness at the injection site. This occurs in about 10 to 30% of recipients.
