This extension study is conducted to assess the efficacy of the GSK 580299 vaccine against cervical intraepithelial neoplasia (CIN) lesions, cervical cancer and cytological abnormalities associated with human papillomavirus (HPV)-16 and/or HPV-18 or other oncogenic HPV types for an additional two years. All subjects who participated in the primary vaccination study NCT00316693 and who confirmed their interest in participating in a long term follow up study will therefore be invited to be followed for up to 48 months after administration of the first dose of vaccine. In addition, safety and persistence of the humoral immune response will be evaluated in this study. This protocol posting deals with objectives \& outcome measures of the extension phase at Months 36 and 48. The objectives \& outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00316693).

For single type: Subjects DNA negative at Month 0 and Month 6 and seronegative at Month 0 for the corresponding HPV type. For combined types: Subjects DNA negative at Month 0 and Month 6 and seronegative at Month 0 for at least one HPV type.
Time frame: From Month 0 up to Month 12
Number of Subjects Reporting Cytologically Confirmed Abnormalities and Lesions Concurrently Associated With Any Oncogenic HPV Types.

Time frame: From Month 0 up to Month 12
Number of Subjects Reporting CIN1+ Associated With Any Oncogenic HPV Types Detected Within the Lesional Component of the Cervical Tissue Specimen.

Time frame: From Month 0 up to Month 12
Number of Subjects Reporting Incident Cervical Infection Associated With HPV-16 and/or 18.
For single type: Subjects DNA negative at Month 0 and Month 6 and seronegative at Month 0 for the corresponding HPV type. For combined types: Subjects DNA negative at Month 0 and Month 6 and seronegative at Month 0 for at least one HPV type.
Time frame: From Month 0 up to Month 12
Number of Subjects Reporting Incident Cervical Infection With Any Oncogenic HPV Types.
HR=High-risk HPV-types: HPV-16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68.
Time frame: From Month 0 up to Month 12
Number of Subjects Reporting Persistent Long-term Cervical Infection (12-month Definition) With HPV-16 and/or 18.
Persistent infection (12-month definition): detection of at least 2 positive HPV DNA PCR assays for the same viral genotype with no negative DNA sample between the 2 positive DNA samples, over an approximate interval of 12 months (\>300 days).
