Brief Title

A Study to Test the Safety and Effectiveness of an Investigational Vaccine in Infants (V419-002)

Official Title

Safety, Tolerability, and Immunogenicity of Four Different Formulations of a Liquid Hexavalent Combination Vaccine, HR5I (Haemophilus Influenzae Type b Conjugate, Recombinant Hepatitis B Surface Antigen, Diphtheria Toxoid, Tetanus Toxoid, 5-Component Acellular Pertussis Vaccine, and Inactivated Poliovirus Type 1, 2, and 3), When Administered to Healthy Hepatitis B Vaccine-Naïve Infants at 2, 3, 4, and 12 to 14 Months of Age

5. Study Description

Brief Summary

The purpose of this study is to evaluate the safety, tolerability and immunogenicity of 4 different formulations of the HR5I vaccine (Haemophilus influenzae type b conjugate, recombinant hepatitis B surface antigen, diphtheria, tetanus, 5-component acellular pertussis, and inactivated poliovirus Types 1, 2, and 3). The primary hypothesis is that at least 1 of the 4 formulations of HR5I administered as a primary series at 2, 3, and 4 months of age will be acceptable (similar to targeted rates) with respect to Postdose 3 antibody responses to all antigens.

Detailed Description

Participants will be randomized into 4 arms: AR51 (12, 10): arm receiving vaccine formulation containing 12 mcg of polyribosylribitol phosphate (PRP) conjugates to tetanus toxoid (PRP-T) and 10 mcg of Hepatitis B surface antigen (HBsAg) PR51 (3, 10): arm receiving vaccine formulation containing 3 mcg of PRP conjugated to the outer membrane protein complex of Neisseria meningitides (PRP-OMPC) and 10 mcg of HBsAg PR51 (6, 10): arm receiving vaccine formulation containing 6 mcg of PRP-OMPC and 10 mcg of HBsAg PR51 (6, 15): arm receiving vaccine formulation containing 6 mcg of PRP-OMPC and 15 mcg of HBsAg
