Clinical Trial Summary

To evaluate Immunogenicity and Safety of Adjuvant and Adjuvant-Free Meningococcal Groups A and C and Haemophilus b Conjugate Vaccine in Infants 2 to 5 Months of Age.

Primary objective:

- To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C and Haemophilus influenzae type b following the administration of adjuvant-free MenAC-Hib conjugate vaccine compared to those observed following the administration of adjuvant MenAC-Hib conjugate vaccine.

- To describe the safety profile of adjuvant-free MenAC-Hib conjugate vaccine compared to that of adjuvant MenAC-Hib conjugate vaccine.

Secondary objective:

•To compare the antibody level of meningococcal serogroups A, C and Haemophilus influenzae type b following the administration of adjuvant-free MenAC-Hib conjugate vaccine to those observed following the administration of adjuvant MenAC-Hib conjugate vaccine.
