Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MenACWY3

Subjects received a 2-dose primary series at 2 and 4 months of age and a toddler dose at 12 months of age.

Group Type EXPERIMENTAL

MenACWY-CRM

Intervention Type BIOLOGICAL

This group received a 2-dose primary series at 2 and 4 months of age and a toddler dose at 12 months of age.

Routine Vaccines

Intervention Type BIOLOGICAL

Each 0.5 mL dose of the pneumococcal 13-valent conjugate vaccine (diphtheria CRM197 protein) is formulated to contain approximately 2.2 μg of each of Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F, 23F saccharides.

MenACWY4

All the subjects received a 3-dose primary series at 2, 4 and 6 months of age and a toddler dose at 12 months of age. Approximately half of the subjects had serum collected at Month 3, and the remainder had serum collected at Month 4.
