Type	Measure	Description	Time frame	Safety issue
Primary	Number of subjects with Adverse Events (AEs)	Subjects with solicited and unsolicited AEs	From Day 0 to Month 7
Primary	Number of subjects with Severe adverse events (SAE)	SAEs assessed include medical occurrences that results in death, are life threatening, require hospitalization or prolongation of hospitalization, results in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subjects.	From Day 0 to Month 12
Secondary	Number of subjects receiving the 3-doses scheduled vaccination with antibody responses as assessed by Geometric mean titer (GMT)	Immunogenicity were assessed by the GMT of anti HPV6/11/16/18/33/45/52/58 neutralizing antibodies after day 31 post last dose, among the subjects who were aged 9-45	day 31 post last dose
Secondary	Number of subjects receiving the 3-doses scheduled vaccination with antibody responses as assessed by seroconversion rate	Immunogenicity were assessed by the seroconversion rate of anti HPV6/11/16/18/33/45/52/58 neutralizing antibodies after day 31 post last dose, among the subjects who were aged 9-45 and seronegative before vaccination	day 31 post last dose
