Summary
This study is designed to assess the immunogenicity and safety of DTaP vaccine (BK1301) as a booster dose in adolescents.
The purposes of this study are as follows:
* To confirm the non-inferiority of BK1301 to Adsorbed Diphtheria-Tetanus Combined Toxoid (DT toxoid) with respect to booster responses for anti-diphtheria toxoid (anti-D) and anti-tetanus toxoid (anti-T) antibodies
* To confirm that booster responses for anti-pertussis toxoid (anti-PT) and anti-Filamentous Hemagglutinin (anti-FHA) antibodies are more than 80% of participants received BK1301
