Effects of a Vaginal Contraceptive Ring on Vaginal Microbiota and Local Immunity
November 16, 2021 updated by: Christine Johnston, University of Washington
To assess potential benefits associated with both intermittent (use for 3 weeks, remove for 1 week, as defined in the package insert) and continuous (use for 4 weeks, then replace) CVR use among women either with BV or at high risk for BV.
The investigators will also recruit women who are HSV2-infected.
