  • Incidence of Persistent HPV 16 Infection [ Time Frame: Through Month 48 ]
    Cases of persistent infection were those with detection of HPV 16 by PCR (Polymerase chain reaction) on at least 2 consecutive visits at least 4 months apart; or detection of HPV 16 in a cervical biopsy specimen showing pathologic evidence of CIN1 (Cervical intraepithelial neoplasia), CIN2 or CIN3 together with HPV 16 detected at the visit immediately before or after the biopsy; or detection of HPV 16 on a subject's last visit.
  • Incidence of HPV 16-related CIN1, CIN2 or C1N3 [ Time Frame: Through Month 48 ]
    Cases of HPV 16-related CIN1, CIN2 or CIN3 are those with detection of HPV 16 in a cervical biopsy specimen showing pathologic evidence of CIN1, CIN2 or CIN3 together with HPV 16 detected at the visit immediately before or after the biopsy.
  • Serum Anti-HPV 16 Geometric Mean Titers [ Time Frame: Month 7 ]
    The limit of detection of the assay was 6 mMU/ml. Samples with titer below the limit of detection were assigned a value of 3 for calculation of GMT and confidence interval. GMTs and confidence limits below the limit of detection are shown as "6.0".
