Study Endpoints
Primary Endpoints
Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Neutralizing Antibodies
At Month 7

Titers are displayed as Geometric Mean Titers (GMTs). The titer is the serum dilution giving a 50 percent reduction of the signal compared to a control without serum.

Secondary Endpoints
Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Neutralizing Antibodies
At Month 6, 7, 12, 18, 24, 36, 48 and 60
Number of Subjects With Antibody Titers (Neutralizing Assay) Against Other Oncongenic HPV Types Greater Than or Equal to the Cut-off Value
At Month 7
