This study explored the level of knowledge and attitudes toward hepatitis B virus (HBV) infection and vaccination of adolescents in juvenile detention facilities and in schools in South Korea. A cross-sectional comparison design with a convenient sampling method was used. Participants in the study were 301 delinquent and 410 school adolescents.
