A<unk> tion certificate issued by the Soviet Union. People most at risk of contracting the virus should be vaccinated. Woodcutters working in tropical areas should be particularly targeted for vaccination. Insecticides, protective clothing, and screening of houses are helpful, but not always sufficient for mosquito control; people should always use an insecticide spray while in certain areas. In affected areas, mosquito control methods have proven effective in decreasing the number of cases. Travellers should have the vaccine ten days prior to being in an endemic area. On 17 May 2013, the World Health Organization (WHO) Strategic Advisory Group of Experts on immunization (SAGE) announced that a 'booster' dose of<unk><unk>  (YF) vaccine, ten years after a primary dose, is not necessary. Since<unk> tion began in the 1930s, only 12 known cases of<unk><unk>  post-vaccination have been identified, after 600 million doses have been dispensed. Evidence showed that among this small number of "vaccine failures", all cases developed the disease within five years of vaccination. This demonstrates that immunity does not decrease with time. Schedule The World Health Organization recommends the vaccine between the ages of 9 and 12 months in areas where the disease is common. Anyone over the age of nine months who has not been previously immunized and either lives in or is traveling to an area where the disease occurs should also be immunized.
