title: Travel immunizations.
abstract: Advising travelers on vaccine-preventable illnesses is increasingly becoming the responsibility of primary care physicians. The approach to vaccine recommendations should be based on a thorough assessment of the risks for travel-related diseases, the time available before trip departure, and current knowledge of the epidemiology of vaccine-preventable diseases. Routine childhood vaccinations should be reviewed in all travelers and updated as necessary. Yellow fever vaccination may be required for entry by countries that lie within a yellow fever zone or for travelers coming from an endemic area to prevent introduction of the disease. Immunization against hepatitis B virus should be considered in travelers who expect to have close contact with local populations that have high rates of hepatitis B transmission. Japanese encephalitis vaccine should be offered to travelers who plan prolonged trips to rural areas in southeast Asia or the Indian subcontinent during the transmission season. Typhoid fever immunization is recommended for travelers who may be exposed to potentially contaminated food and drink. Preexposure rabies vaccination should be considered in travelers who plan a prolonged duration of stay in a remote area or who engage in activities that might involve working near animals or that could attract animals. Physicians should be aware of the adverse events and contraindications associated with each travel vaccine.
