Recommendations for administering hepatitis A vaccine to contacts of international adoptees.Pediatrics. 2011 Oct; 128(4):803-4.Ped
The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the American Academy of Pediatrics (AAP) recommend routine administration of hepatitis A vaccine for household members and close contacts, including baby-sitters, when children are adopted from countries with high or intermediate rates of hepatitis A infection. This policy expands previous AAP recommendations to immunize travelers to countries who are seeking to adopt a child in countries with high or medium hepatitis A endemicity. All previously nonimmune unvaccinated people who anticipate close exposure to international adoptees during the 60 days after their arrival should receive hepatitis A immunization, ideally 2 or more weeks before the arrival of the adopted child.
