title: [A preliminary study on response to hepatitis B vaccine in subjects with various levels of antibody to hepatitis B surface antigen].
abstract: After hepatitis B vaccine immunization, serum antibody response was of primary type in 33 cases with anti-HBs less than 2.1 S/N (S/N Ratio Unit) at T0, the anti-HBs positive rate was 39.4%, 84.8%, 96.7% and 96.7% in T1, T2, T0 and T12 respectively. Anti-HBs S/N rose gradually month by month, the antibody response in younger children was better than that in adult. Anamnestic type in 38 cases with anti-HBs greater than 2.1 S/N at T0, the antibody levels rose rapidly in T1, T2 and began to fall in T8. The children were negative for HBsAg, anti-HBs and anti-HBc in sera by RPHA, PHA and ELISA respectively, most (100% in 1-4 age group and 63.2% in 5-9 age group) of them were also negative for HBV serological markers by SPRIA repeatedly, thus they were susceptible and need for hepatitis B vaccine immunization. Indication of hepatitis B vaccination for adult population was also discussed.
