Tritanrix-HepB/Hiberix Group
Subjects vaccinated with 3 doses of Tritanrix-HepB/Hiberix vaccine in the primary study (NCT00317122), were boosted in the current study with one dose of the same vaccine at 15 to 18 months of age, intramuscularly into the anterolateral quadrant of the left thigh or upper region of the left arm. Subjects were also administered one booster dose of Mencevax ACW vaccine at 24 to 30 months of age by deep subcutaneous injection in the upper region of the left arm.

Population: The analysis were performed on the Booster ATP cohort for immunogenicity which included all evaluable subjects who received the 3 vaccine doses in the primary vaccination study, received one of the two vaccines according to the protocol in this booster study and for whom data concerning immunogenicity measures were available.

Vaccine response was defined as follows: for initially seronegative subjects (i.e. with rSBA titre \< 1:8 pre-vaccination), rSBA titre ≥ 1:32 post-vaccination (seroconversion), and for initially seropositive subjects (i.e. with rSBA titre ≥ 1:8 pre-vaccination), at least a 4-fold increase in rSBA titre from pre to post-vaccination.
