Background: Cervical cancer is a major public health concern in China. We report the end-of-study results of a phase II/III trial to assess the efficacy, immunogenicity, and safety of the AS04-human papillomavirus (HPV)-16/18 vaccine in Chinese women aged 18-25 years followed for up to 72 months after first vaccination. Results of approximately 57 months following first vaccination have been previously reported.
