Primary outcomePrimary: Geometric Mean Antibody Titers Following the Third Dose of Human Papilloma Virus (HPV) Vaccine by Virus Type and by Administration Schedule — 1894; 4221; 1773; 5623 milliMerck units per mL — p=.025

Summary

This is a randomized, open label trial of HPV (human papilloma virus) vaccine, comparing an on-time administration of the third dose with delayed administration of the third dose. All participants would receive the first and second doses according to schedule. They would be randomized to either vaccine at 6 months or vaccine at 12 months. Blood will be drawn for titers twice from all participants: pre-dose 1 and one month post third dose. We hypothesize that the GMTs in the test group (T) are non-inferior to the usual timing control group (C): H0: δ ≤ -δ0 versus H1: δ > -δ0 where δ = log (GMTT )- log (GMTC) and δ0 is the pre-specified non-inferiority margin.
