Immunization of girls against oncogenic human papillomavirus (HPV) types before sexual debut is important for cervical cancer prevention. This phase III blinded, randomized, controlled trial in adolescent girls assessed safety of the HPV-16/18 AS04-adjuvanted vaccine.
The HPV-16/18 AS04-adjuvanted vaccine was generally well tolerated and immunogenic when administered to young adolescent females, the primary target of organized vaccination programs.
