This phase 3 study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese females aged 9 to 45 years


This study (protocol 9-HPV-3003) is an immunogenicity and safety study in the subjects (9-19 years of age) who received the 9-valent HPV recombinant vaccine compared with the subjects (20-45 years of age). In this study, we will assess whether the immunogenicity of the 9-valent HPV vaccine given 3-dose schedule in the subjects (9-19 years of age) in noninferior to that in the subjects (20-45 years of age) receiving 3 doses, while assessing the safety of this vaccine.
