Brief summary

This study will be conducted in three stages. In the DTP booster stage at 15 to 24 months of age, all subjects will receive a booster dose of Tritanrix™-HepB/Hiberix™. In the Mencevax™ ACWY full dose stage at 24 to 30 months of age all subjects will receive a dose of Mencevax™ ACWY. In the Mencevax™ ACWY small dose stage at 30 to 36 months of age, the first 75 subjects in each of the two centers will be tested for boostability of the MenA and MenC immune response by giving a fifth of a dose of a Mencevax™ ACWY vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Detailed description

Subjects in the group that was previously primed with Tritanrix™-HepB/Hiberix™ will be the control group for the group that was previously primed with Tritanrix™-HepB/Hib-MenAC. Blood samples will be drawn from subjects as follows: * prior to and one month after the full dose of the Mencevax™ ACWY vaccine. * prior to and one month after 1/5th of a dose of Mencevax™ ACWY vaccine (only for the first 75 subjects in each of the two centers).

Interventions

Number of Subjects With Vaccine Response for rSBA-Men A, C

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

Time frame: 1 month after Mencevax ACWY vaccination (at 25 to 31 months of age).

Population: The analysis were performed on the Booster ATP cohort for immunogenicity which included all subjects who had received 3 doses in the primary vaccination study, who had received a single dose of MenACWY according to protocol at 24 to 30 months of age and for whom data concerning immunogenicity measures were available.
