Phase III Study Comparing the Immunogenicity of 9-valent HPV Recombinant Vaccine and Gardasil-9

A Phase III, Randomized, Blinded, Positive-controlled Study to Compare the Immunogenicity of Zerun 9-valent Human Papillomarivus (Types 6, 11, 16, 18, 31, 33, 45, 52 and 58) Recombinant Vaccine (Pichia Pastoris) in Healthy Female Subjects Aged 16-26 Years.

This study will evaluate the immunogenicity and safety of Zerun 9-valent HPV recombinant vaccine in healthy female 16-26 years of age by comparing with GARDASIL®9.
