Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to:

* (cohort 1) evaluate safety and immunogenicity (Haemophilus influenzae type b, Hib) of BK1310.
* (cohort 2) evaluate efficacy and safety of BK1310 using ActHIB® and Tetrabik as a control in healthy infants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

\<Cohort 1\>

* Arm: BK1310-High. Intervention: DPT-IPV-Hib-High(Combined Vaccine) 0.5mL, subcutaneous injection, 3 times with the 3-8weeks intervals then an additional injection after 6-13 months.
* Arm: BK1310-Low. Intervention: DPT-IPV-Hib-Low(Combined Vaccine) 0.5mL, subcutaneous injection, 3 times with the 3-8weeks intervals then an additional injection after 6-13 months.

\<Cohort 2\>

* Arm: BK1310-High or Low. Intervention: DPT-IPV-Hib-High(Combined Vaccine) or DPT-IPV-Hib-Low(Combined Vaccine) 0.5mL, subcutaneous injection, 3 times with the 3-8weeks intervals.
* Arm: ActHIB® and Tetrabik. Intervention: Hib vaccine and DPT-IPV 0.5mL, subcutaneous injection, 3 times with the 3-8weeks intervals.
