Intervention / Treatment |
---|---|
Experimental: Infanrix-hexa/Engerix-B Group
Subjects aged 11-12 year old received 3 doses of Infanrix-hexa vaccine in the primary study (217744/031 (NCT01457495)) and a challenge dose of Engerix-B vaccine in this study.
Engerix-B was administered as a single dose intramuscularly into the deltoid region of the non-dominant arm.

Active Comparator: Infanrix-IPV+Hib/Engerix-B Group
Subjects aged 11-12 year old received 3 doses of Infanrix-IPV+Hib and Engerix-B vaccines in the primary study (217744/031 (NCT01457495)) and a challenge dose of Engerix-B vaccine in this study.
Engerix-B was administered as a single dose intramuscularly into the deltoid region of the non-dominant arm.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Number of Subjects With Anti-hepatitis B (Anti-HBs) Antibody Concentration Equal to or Above (≥) 100 Milli-International Units Per Milliliter (mIU/mL)
Time Frame: One month after a challenge dose of Engerix-B vaccine
|
A decrease in the specificity of the anti-HB enzyme-linked immunosorbent assay (ELISA) had been observed in some studies for low levels of antibody (10-100 mIU/mL).
All the available blood samples initially tested with ELISA were re-tested using the Chemi Luminescence Immuno Assay (CLIA) approved by the US Food and Drug Administration (FDA).
The table shows updated results following partial or complete retesting/reanalysis.
