Study Summary

This trial compares the effectiveness of intramuscular and intradermal fractional doses of two HPV vaccines among men and women in Seattle, with immune response assessed over one year.

Who is the study for?
This trial is for men and women aged 27-45 in Seattle who haven't had the HPV vaccine and won't get it during the study. They must be able to give consent, attend follow-ups, and not have HIV, recent chemo or immunosuppression drugs, unstable health conditions like severe high blood pressure or diabetes, a history of HPV cancer, known allergies to vaccine ingredients, or significant immune system diseases.Check my eligibility
What is being tested?
The study compares two ways of giving a smaller-than-usual dose of HPV vaccines: one group gets the bivalent vaccine intramuscularly (in the muscle) or intradermally (under the skin), while another gets a fractional dose of nonavalent vaccine. The participants' immune responses are checked over a year at set times after vaccination.See study design
What are the potential side effects?
Possible side effects from fractional doses of HPV vaccines may include local reactions at injection site such as pain and swelling, general symptoms like fever or headache. Serious allergic reactions are rare but can occur especially in those with known allergies to components.
