- 12M12B14B (2b) (Type: EXPERIMENTAL): Previously in the parent study subjects ahd received three doses of routine vaccine at 2, 4 and 6 months of age, respectively. These subjects received two catch-up doses of rMenB+OMV NZ at 12 and 14 months of age and one dose of MMRV vaccine given concomitantly at 12 months of age in the present study.
- 12B12M (3a) (Type: EXPERIMENTAL): Previously in the parent study subjects had received three doses of rMenB+OMV NZ at 2, 4 and 6 months of age respectively.

- 12B13M (3b) (Type: EXPERIMENTAL): Previously in the present study subjects had received three doses of rMenB+OMV NZ at 12 months of age respectively. These subjects one booster (fourth) dose of rMenB+OMV NZ at 12 months of age and one dose of MMRV vaccine at 13 months of age in the present study.
- 12B12M_C (4a) (Type: EXPERIMENTAL): Previously in the parent study subjects had received three doses of Meningococcal C vaccine and routine vaccine at 2, 4 and 6 months of age respectively. These subjects had received one single dose of rMenB+OMV NZ at 12 months of age concomitantly with one dose of MMRV vaccine in the present study.
- 12B13M_C (4b) (Type: EXPERIMENTAL): Previously in the parent study subjects had received three doses of Meningococcal C vaccine and routine vaccine at 2, 4 and 6 months of age. These subjects received one single dose o rMenB+OMV NZ at 12 months of age and one dose of MMRV vaccine at 13 months of age in the present study.
