Reporting Groups
| Description | |
|---|---|
| Group 1 - Base Study Quadrivalent Human Papillomavirus Vaccine |
The Vaccination Period for the base study encompassed Day 1 through Month 7, during which time study subjects in Group 1 were vaccinated (at Day 1, Month 2 and Month 6) with the Quadrivalent Human papillomavirus (HPV) vaccine. The Follow-up Period for the Base Study encompassed the follow-up of subjects who had received the Quadrivalent HPV vaccine; from completion of the Vaccination Period at Month 7 through Month 48 of the study. |
| Group 2 - Base Study Monovalent HPV (Type 16) Vaccine |
The Vaccination Period for the base study encompassed Day 1 through Month 7, during which time study subjects in Group 2 were vaccinated (at Day 1, Month 2 and Month 6) with the Monovalent (HPV 16) HPV vaccine. The Follow-up Period for the Base Study encompassed the follow-up of subjects who had received the Monovalent (HPV 16) HPV vaccine; from completion of the Vaccination Period at Month 7 through Month 48 of the study. Group 2 Base Study Monovalent HPV (Type 16) Vaccine was not part of the pre-specified efficacy analysis population. |
| Group 3 - Base Study Placebo |
The Vaccination Period for the base study encompassed Day 1 through Month 7, during which time study subjects in Group 3 were vaccinated (at Day 1, Month 2 and Month 6) with placebo. The Follow-up Period for the Base Study encompassed the follow-up of subjects who had received placebo; from completion of the Vaccination Period at Month 7 through Month 48 of the study. |
| Group 4 - Quadrivalent Human Papillomavirus Vaccine Extension | This group includes 844 subjects who entered the extension including subjects who in the base study received fewer than the full three doses of Quadrivalent HPV vaccine during the base study (i.e., subjects who received placebo in the base study; subjects who received monovalent [type 16] HPV vaccine in the base study, or subjects who received ≥ 2 doses of quadrivalent HPV vaccine in the base study). Subjects who discontinued the base portion of the study could enter the extension portion of the study. In the extension period subjects designated as "Completed Period" are those who received three doses of quadrivalent HPV vaccine and completed all required follow-up visits. Subjects designated as "Not Completed" are those who: a) Received all three vaccinations, but did not complete follow-up; b) Did not receive all vaccinations, but completed follow-up, or c) Did not receive all vaccinations, and did not complete follow-up). |
