Interventions |
Biological: Gardasil, human papillomavirus (type 6, 11, 16, 18) recombinant vaccine Biological: Matching Placebo |
Enrollment | 12167 |
Participant Flow
Recruitment Details | Female participants were randomized to receive quadrivalent human papillomavirus (qHPV) vaccine (GARDASIL™) or placebo in the Base Study (V501-015, NCT00092534), and were followed for 4 years. Participants who received placebo in the Base Study were eligible to receive the 3-dose qHPV vaccine series during the Base Study Extension (EXT). |
Pre-assignment Details |
Participants who received 3 doses of qHPV vaccine either during the Base Study or Base Study EXT were eligible for enrollment in the Long-Term Follow-Up (LTFU) Study (V501-015-21). The 10-year-long registry-based LTFU was conducted at 4 National Registry Study Centers (NRSC) in Denmark, Iceland, Norway, and Sweden. |

During the Base Study, participants received 3 qHPV vaccinations (at Day 1, Month 2 and Month 6) and were followed for up to 4 years. | During the Base Study, participants received 3 placebo vaccinations (at Day 1, Month 2 and Month 6) and were followed for up to 4 years. | Participants who received placebo (N=581) or an incomplete qHPV vaccine regimen (N=13) were enrolled to receive qHPV vaccine during the base study extension; participants designated as "Not Completed" are those who did not complete all three vaccinations and/or all required follow-up visits. | Participants who received qHPV vaccine in the Base Study with approximately 4 years of follow-up in the Base Study and 10 years of follow-up in the LTFU. Cohort 1 provided a total of approximately 14 years of follow-up post-vaccination. | Participants who received placebo in the Base Study and qHPV vaccine after completion of the Base Study and prior to entry into the LTFU. Cohort 2 provided a total of approximately 10 years of follow-up post-vaccination. |
