|Estimated Study Completion Date :||December 2014|
Subjects with an on-time interval between Dose 1 and 2 and an on-time interval between Dose 2 and 3.
Experimental/Primary Arm 3
This primary arm will consist of subjects receiving the second dose substantially late/third dose substantially late.
Experimental/Primary Arm 2
This primary arm will consist of subjects receiving the second dose substantially late/third dose on time.
Experimental/Primary Arm 1
This primary arm will consist of subjects receiving the second dose on time/third dose substantially late.
Subjects who meet eligibility requirements but do not fit into any of the primary experimental arms.
- Geometric mean titer (GMT) to vaccine human papillomavirus (HPV) serotypes. [ Time Frame: One month after the third HPV vaccine dose. ]
- Sero-response rate (proportion of subjects developing antibody to vaccine HPV serotypes). [ Time Frame: One month after the third HPV vaccine dose. ]
- GMT to vaccine HPV serotypes as measured by anti-HPV cLIA. [ Time Frame: Prior to the third HPV vaccine dose and six months after the third HPV vaccine dose. ]
- Sero-response rate (proportion of subjects developing antibody to vaccine HPV serotypes). [ Time Frame: Prior to the third HPV vaccine dose and six months after the third HPV vaccine dose. ]
