Study Summary

This trial is to see if a third dose of the HPV vaccine is necessary for people aged 15-26, or if two doses provide enough protection against the nine types of HPV it vaccinates against.

Who is the study for?
This trial is for males and females aged 15-26 who haven't had any HPV vaccine doses. They must be able to consent (with parent's consent if under 18), have a way to pay for the vaccine, speak English or Spanish, and have reliable phone access. It's not for those with many sexual partners, immune/autoimmune disorders, bleeding disorders, pregnant women or those planning pregnancy/birth control non-users.Check my eligibility

The study is testing whether two doses of the Gardasil 9 HPV vaccine are as effective as three in preventing infection from nine types of HPV in young people. Participants will either receive the standard three-dose schedule or a two-dose schedule with a delayed third dose.See study design
What are the potential side effects?
Possible side effects of the Gardasil 9 vaccine include pain at injection site, swelling, redness, headaches, fever, nausea and dizziness. Rarely there might be allergic reactions due to components like aluminum or yeast.
