About this study

Open multicentre study with 4 treatment groups. Two groups will receive the 134612 vaccine with Priorix-Tetra either at the same or different visits followed by a second Priorix-Tetra vaccination at 84 days.

Two control groups will receive Priorix-Tetra and Meningitec at different visits followed by a second Priorix-Tetra vaccination at 84 days.

For all subjects, two blood samples will be taken: prior to and 42 days after the first vaccination. In a subset (30% of subjects in Groups A en C) from selected study centres: additional sample 42 days after second Priorix-Tetra dose.
