Before you go, know which immunizations are required for entry into your countries of destination and how to stay healthy once you are there.  As the saying goes,  "an ounce of prevention is worth a pound of cure", so be aware that the San Francisco Department of Public Health's Adult Immunization and Travel Clinic can provide pre-trip counseling and immunization services to help ensure that you arrive back home with nothing more than the usual jet lag.
