Vaccination requirements and suggestions vary by country. The Center for Disease Control (CDC) in Atlanta has an International Traveler’s Hotline that provides up-to-date vaccination requirements for any region or country you select. Call Traveler’s Health Hotline at 1-800-394-8747, or visit the CDC web site. We urge students to research vaccinations and health precautions for any areas they plan to visit outside of their host country.
