Immunization. Around the world in 80 shots.

Physicians counseling patients who are planning major travels should make sure that baseline immunizations (diphtheria-tetanus-pertussis, polio, measles, rubella) and any necessary boosters are current. In addition, several other immunizations may be warranted (yellow fever, typhoid, and cholera), depending on destination(s) and itinerary, and prophylaxis for malaria may be advisable. As worldwide requirements for immunization do change, the physician should verify current requirements before planning an immunization schedule for a particular patient.
