Travelers should note that preparations manufactured in foreign countries may or may not meet these requirements. Persons needing repeat doses in other countries should use products that meet U.S. license requirements. CDC recommends hepatitis A vaccine or IG for protection against hepatitis A. Hepatitis A vaccine is available in both pediatric and adult formulations with different dosages and schedules. Your health care provider should be consulted for correct dosage and scheduling. The vaccine series must be completed for long-term protection.
Immune globulin is recommended for persons of all ages who desire only short term protection.
Strict food and water precautions are also recommended. Babies born to HIV-infected women may become infected before, during, or shortly after birth through breast feeding. In the United States, all donations of blood and plasma are screened for HIV with several tests, but this screening may not take place in all countries. Scientific studies have revealed no evidence that HIV is transmitted by air, food, water, insects, inanimate objects, or casual contact. Specific medical treatment clearly improves the health and the survival of HIV infected persons, but there is no vaccine available.
