Although the hepatitis A vaccine is usually only given to travelers who intend to take multiple trips abroad or who stay longer than three months, Dr. Stanely Lemon, Department of Microbiology and Immunology at the University of Texas-Galveston, recommends the vaccine for everyone because more and more people are traveling repeatedly to high risk countries. Since the traveler should receive the vaccine at least two weeks ahead of time, and some health professionals recommend four weeks, the traveler must start preparing for travel earlier than if he or she were receiving the intramuscular immunoglobulin. The initial hepatitis A immunization will last twelve months, and can be extended for several years with a booster. Unfortunately, if a traveler does contract HAV, they might not know it. HAV has a long incubation period - it can take two to six weeks before symptoms emerge.
