Inclusion criteria

1. Subject is female between and including 9-26 years of age, or male between and including 9-17 years of age at the first vaccination; 2. Subject (and their legal guardian) is able to understand and comply with the requirements of the protocol(e.g. biological specimen collection, completion of the diary cards, return for follow-up visits), and written informed consent must be obtained from the subject prior to enrollment; 3. Adolescent female subject who agrees to practice effective contraception within 8 months after the first vaccination or has undergone tubal ligation,subtotal hysterectomy for benign lesion, ovarian benign tumor resection; 4. No previous history of sexually transmitted diseases (including syphilis, gonorrhea, chancroid, venereal lymphogranuloma, groin granuloma, etc.); 5. Male, or female without previous history of abnormal cervical screening results or cervical intraepithelial neoplasia (CIN);

Exclusion criteria

Subject has used of any investigational or non-registered product (drug or vaccine) within 30 days preceding the first dose of study vaccine or plans to use during the study period , or has participated in another clinical research in the past two years, or plans to participate in another research during the study period; 4. Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs or systemic corticosteroids (Except intranasal steroid, the use of low dose topical, ophthalmic and inhaled steroid preparations will be permitted.) within 6 months prior to vaccination. 5. Administration of immunoglobulin and/or blood products within 3 months prior to vaccination or planned to use them within 7 months after the first dose. 6. Administration of inactivated vaccine within 14 days prior to vaccination or live vaccine within 21 days; 7.

Subject has received other HPV vaccines or participated in clinical research related to HPV or cervical cancer previously; 9. Subject has severe immunodeficiency disease, severe primary disease of important viscera, cancer and autoimmune disease (including systemic lupus erythematosus, rheumatoid arthritis, asplenia or splenectomy due to any condition, and other immunological diseases that investigators believe may influence the immune response). 10. History of severe allergy (e.g., anaphylaxis, generalized urticaria, dyspnea, angioedema, and other significant reaction) to any previous vaccination, or be allergic to any of the components of the study vaccines. 11.

Design outcomes

Primary

MeasureTime frameDescription
Immunogenicity1: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at Months 7 in the population aged 9-26 years old receiving 3 doses of the nonavalent vaccine7 months after the first doseTo determine whether the immune responses (antibodies to HPV-6, 11, 16, 18, 31, 33, 45, 52, and 58) at month 7 (one month after the final dose) in the population aged 9-17 years receiving 3 doses of the nonavalent vaccine are noninferior to those in women aged 18-26 years receiving 3 doses of vaccine.

Secondary

MeasureTime frameDescription
Immunogenicity2: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at Months 7 in the population aged 9-14 years old receiving 2 doses of the nonavalent vaccine7 months after the first doseTo determine whether the immune responses (antibodies to HPV-6, 11, 16, 18, 31, 33, 45, 52, and 58) at month 7 (one month after the final dose) in the population aged 9-14 years receiving 2 doses of the nonavalent vaccine are noninferior to those in women aged 18-26 years receiving 3 doses of vaccine.
Safety1: Local and systematic adverse events/reactions occurred within 7 days after each vaccination.During the 7-day period following each vaccinationLocal and systematic adverse events/reactions occurred within 7 days after each vaccination.
Immunogenicity3: Anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 type specific antibody levels at months 18 and 30 in the population aged 9-14 and 15-17 years old receiving 2 doses or 3 doses of the nonavalent vaccine30 months after the first doseTo determine the immune persistence (antibodies to HPV-6, 11, 16, 18, 31, 33, 45, 52, and 58) at months 18 and 30 in the population receiving 2 doses or 3 doses of the nonavalent vaccine
Safety3: Severe adverse events occurred throughout the study.Up to 8 monthSevere adverse events occurred throughout the study. To evaluate number of SAEs between the different arms.
Safety4: Pregnancy and pregnancy outcome.Up to 8 monthPregnancy and pregnancy outcome. To evaluate number of births and terminations between the different arms.
Safety2: Adverse events/reactions occurred within 30 days after each vaccination.Within 30 days (Day 0-30) after any vaccinationAdverse events/reactions occurred within 30 days after each vaccination.
