    The strategy to eliminate hepatitis B virus (HBV) transmission in the United States is comprised of the following components : (1) preventing perinatal transmission. (2) routine infant vaccination. (3) catch-up vaccination of children in high-risk groups at any age, (4) catch-up vaccination of all children at 11. 12 years of age and (5) vaccination of adolescents and adults in high-risk groups.

    According to recent surveys.>85% of pregnant women are screened for hepatitis B surface antigen (HBsAg).

    Of infants horn to HBsAg-positive women identified in 1995,93% received appropriate immunoprophylaxis at birth ; however, only 69% were fully vaccinated by 6 8 months of age.

    From 1991 (when routine infant hepatitis B vaccination was first recommended) to 1996, the proportion of 19 35-month-old children who have received three doses of hepatitis B vaccine has increased from<10 to 83%. During this time. rates of acute hepatitis B in children 7 10 years of age have declined by 27% and rates among children 3 6 years of age have declined by 62%. Implementation of programmes for catch-up vaccination of all adolescents at 11 12 years of age and for vaccination of adolescents and adults in high-risk groups have only recently begun and no data are available to assess the progress of these programmes.

    However, 26% (13 ; 50) of states now have laws requiring adolescents to be vaccinated in order to enter school. (...)
