Before attending the Winter Olympics in Sochi, Russia, U.S. health officials recommend travelers ensure their vaccinations are up to date.
Officials at the Centers for Disease Control and Prevention in Atlanta said travelers should make sure they are up-to-date on routine vaccines including: the measles-mumps-rubella vaccine, diphtheria-tetanus-pertussis vaccine, varicella (chickenpox) vaccine, the polio vaccine and a seasonal flu shot.
In addition, the CDC recommends getting the hepatitis A vaccine because people can get hepatitis A through contaminated food or water in Russia, regardless of where they are eating or staying.
