Brief summary

This study is designed to evaluate the vaccine efficacy, immunogenicity and safety of the 9-valent (Types 6, 11, 16, 18, 31, 33, 45, 52 and 58) Human Papillomavirus (HPV) Recombinant Vaccine (Hansenula Polymorpha) in Chinese male subjects aged 18-45 years. The primary hypothesis in the study is the 9-valent HPV recombinant vaccine reduces the incidence of vaccine HPV types-related genital warts compared with placebo in Chinese men.

Detailed description

The primary aim of this clinical trial is to evaluate the efficacy of the 9-valent HPV vaccine in men aged 18-45 years old. It will also learn about the safety and immunogenicity of the 9-valent HPV vaccine. Participants will inoculate the 9-valent HPV vaccine or a placebo according to the 0, 2, 6 month immunization program. Visit the clinic on the 8th and 31st day after each dose of vaccination for the collection of safety information, keeping a diary of their symptoms and medications.

Interventions

BIOLOGICAL9-valent Human Papillomavirus (Types 6, 11, 16, 18, 31, 33, 45, 52 and 58) Recombinant Vaccine (Hansenula Polymorpha)

Subjects received 3 doses of 9-valent HPV vaccine according to a 0, 2, 6-month schedule (0.5 mL intramuscular injection in the deltoid muscle).

BIOLOGICALPlacebo

Subjects received 3 doses of Placebo according to a 0, 2, 6-month schedule (0.5 mL intramuscular injection in the deltoid muscle).
