摘要

All subjects in this clinical study gave informed written consent, and guidelines of the authors' institution regarding human experimentation were observed in the conduct of the study. A booster dose of vaccine given to 18 adolescents (immunized as children) and 7 older adults immunized 13 years earlier with a 3-dose course of recombinant hepatitis B vaccine induced a strong secondary antibody response, demonstrating that the vaccinees retained immunologic memory for HbsAG. Within one week. booster vaccination induced an 11 to 24-fold rise in the GMT of anti-HBs which continued. reaching 52 to 319-fold after 4 weeks. Significantly even the 5 individuals with less than 10 mIU/ml of anti-HBs prior to the booster all had impressive responses to the booster dose.
