About this study

The goal of this clinical trial is to compare a 2-dose and 3-dose series of 9vHPV vaccine among 27-45-year-old females to assess if 2 doses elicit a noninferior immune response. Participants will be randomized 1:1 to either the 2-dose group or the 3-dose group and asked to provide 4 blood samples over a period of 12 months. All 2-dose participants will be offered a 3rd dose after the final blood draw,12 months after their initial vaccination.
