Continuing Decrease in Hepatitis B Virus Infection 30 Years After Initiation of Infant Vaccination Program in Taiwan

摘要

BACKGROUND & AIMS: Taiwan began a universal hepatitis B virus (HBV) vaccination program for infants in July 1984. The seroprevalence of hepatitis B surface antigen (HBsAg) decreased from 9.8% before the vaccination program to less than 1% by 25 years afterward. We continued to monitor HBV infections in this population.
