Primary Objective~To use a randomized controlled trial (RCT) to test an innovative multilevel intervention to increase HPV vaccination rates among young adults.~Secondary Objective(s)~To gain insight into mechanisms of the intervention's efficacy, individual differences, and implementation of the intervention using mixed methods.
The study uses a randomized controlled trial (RCT) to test an innovative multilevel intervention to increase HPV vaccination rates among young adults. The two primary outcomes will be the rate of HPV vaccination initiation by 3-month follow-up and rate of HPV vaccination completion by 9-month follow-up.
