text: What is the yellow fever vaccine?
  The yellow fever vaccine has been used to prevent yellow fever since 1930. The CDC recommends a single-dose shot at least ten days before travel. A booster dose is recommended every ten years before traveling to some high-risk regions (E.g., Ghana). The yellow fever vaccine and International Certificate of Vaccination are given only at designated certified vaccination centers.
