Adolescent BV - Impact of the vaginal microbiome on topical HIV pre-exposure prophylaxis (PrEP)

Updated on 16 February 2023
sexually transmitted infections


Through this study, we hope to learn how healthy bacteria and bacteria associated with a vaginal infection called bacterial vaginosis (BV) affect how PrEP works in women. BV is a common infection in young women that causes itching, odor, vaginal discharge, and inflammation. Women with BV may be at increased risk to become infected with sexually transmitted infections, including HIV. This is why it is important to reduce the number of vaginal infections that people experience and to study how to make PrEP more effective for women.


The study consists of two, three, or four visits, depending on the group they have been assigned, over the course of four to five weeks. Participation involves answering questions about your medical and sexual history, a blood draw, vaginal swabs, HIV and pregnancy testing, and pelvic exams.
