Progress toward elimination of hepatitis B virus transmission in the United States

E E Mast et al. Vaccine. 1998 Nov.

Abstract

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 born 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. Current data indicate that substantial progress has been made in implementing a strategy to eliminate HBV transmission in the United States. Future efforts need to be focused on improving complete immunoprophylaxis of infants of HBsAg-positive mothers, increasing vaccine coverage among 11-12 year old children and implementing programmes to vaccine adolescents and adults in high-risk groups.
