Yellow fever vaccine is a vaccine that protects against yellow fever.[4] Yellow fever is a viral infection that occurs in Africa and South America.[4] Most people begin to develop immunity within ten days of vaccination and 99% are protected within one month, and this appears to be lifelong.[4] The vaccine can be used to control outbreaks of disease.[4] It is given either by injection into a muscle or just under the skin.[4][5]
The World Health Organization (WHO) recommends routine immunization in all countries where the disease is common.[4] This should typically occur between nine and twelve months of age.[4] Those traveling to areas where the disease occurs should also be immunized.[4] Additional doses after the first are generally not needed.[6]
The yellow fever vaccine is generally safe.[4] This includes in those with HIV infection but without symptoms.[4] Mild side effects may include headache, muscle pains, pain at the injection site, fever, and rash.[4] Severe allergies occur in about eight per million doses, serious neurological problems occur in about four per million doses, and organ failure occurs in about three per million doses.[4] It appears to be safe in pregnancy and is therefore recommended among those who will be potentially exposed.[4] It should not be given to those with very poor immune function.[7]
Yellow fever vaccine came into use in 1938.[8] It is on the World Health Organization's List of Essential Medicines.[9][10] The vaccine is made from weakened yellow fever virus.[4] Some countries require a yellow fever vaccination certificate before entry from a country where the disease is common.[4][5]
