International travelers

• Your risk of becoming ill while traveling depends on:
  • Where you're traveling.
  • The length of your stay.
  • Activities planned.
  • Your health.
  • Your vaccine history.
• Because most vaccines take time to become effective and may need to be given in a series over time, you should check with a health care provider familiar with travel medicine or make an appointment at a travel clinic at least four to six weeks before you travel.
  • Not all health care providers or travel clinics offer all vaccines you may need, so be sure to ask which services are available before you make your appointment.
  • Only health care providers authorized by us can give the yellow fever vaccine.
