The Yellow Fever vaccine can prevent Yellow Fever. This vaccine is given only at designated vaccination centers. After vaccination, you will be given a stamped and signed “International Certificate of Vaccination or Prophylaxis” (yellow book). This certificate becomes valid 10 days after vaccination and is good for life. You will need this card as proof of vaccination to enter certain countries.
As Yellow Fever is transmitted by mosquito bites, mosquito avoidance will also minimize risk of infection. The following personal protective measures are therefore also very important:
-wearing clothes that cover most of your body,
-using an effective insect repellent, such as those containing DEET.
