title: Prevention of varicella. Update recommendations of the Advisory Committee on Immunization Practices (ACIP).
abstract: In February 1999, the Advisory Committee on Immunization Practices (ACIP) expanded recommendations for varicella (chickenpox) vaccine to promote wider use of the vaccine for susceptible children and adults. The updated recommendations include establishing child care and school entry requirements, use of the vaccine following exposure and for outbreak control, use of the vaccine for some children infected with the human immunodeficiency virus (HIV), and vaccination of adults and adolescents at high risk for exposure. These recommendations also provide new information on varicella vaccine postlicensure safety data.
