Anti-HBs titre ⩾10 mIU/ml.
An anamnestic response has defined as a rise within 10–28 days in anti-HBs concentrations to ⩾10 mIU/ml in subjects seronegative for anti-HBs antibodies (or with levels <10 mIU/ml) before challenge dose and as an increase in anti-HBs titres in subjects with seroprotective levels of anti-HBs before challenge.
