In September 1987, Taiwan began to use, in its mass vaccination program against Hepatitis B, a plasma-derived hepatitis B vaccine manufactured locally by Lifeguard Pharmaceutical, Inc. To assess both the immunological and the protective effects of this domestically-manufactured hepatitis B vaccine used in the program, the vaccinated children, all aged two years, were grouped into three categories according to the degree of hepatitis B infectivity of their mothers.
