Sex act is defined as penile-vaginal penetrative intercourse. Study staff will provide condoms to all study participants. Participants will not be restricted from engaging in oral sex.~* Has not used pre- or post-exposure prophylaxis for HIV exposure in the 3 months prior to Screening.~* Per participant report at Screening and Enrollment, agrees not to participate in other research studies involving drugs, medical devices, or vaginal products for the duration of study participation.~* At Screening, participant states she is able and willing to refrain from taking traditional herbs or medicines and is willing to refrain from inserting any non-study vaginal products or objects into the vagina, including but not limited to, spermicides, diaphragms, contraceptive vaginal rings, vaginal medications, vaginal probiotics/pre-biotics, menstrual cups, cervical caps (or any other vaginal barrier method), douches, lubricants, vaginal drying agents and sex toys (vibrators, dildos, etc.). Tampons may be used, but for menses only.~* Vaginal and cervical anatomy that, in the opinion of the investigator, lends itself to easy genital tract sample collection.~Exclusion Criteria:~Women must meet none of the following criteria prior to genital sampling at Enrollment:~Participant report of any of the following at Screening:~* Sex in the past 3 months or any possibility of sex during study participation with a partner who is HIV+ or with a partner of unknown HIV status.~* Known adverse reaction to polyurethane or to any components of the study product or allergy to both silver nitrate and Monsel's solution.~* Active hepatitis B infection.~* Chronic, recurrent, and/or acute vulvar or vaginal symptoms (pain, irritation, spotting, etc.).~* Known bleeding disorder that could lead to prolonged or continuous bleeding with biopsy.~* Intending to become pregnant during the period of study participation.~* Currently breastfeeding or planning to breastfeed during the course of the study.~* Menopause.~* History of unexplained or unresolved intermenstrual bleeding in the 3 months prior to screening.~* History of gynecological procedures (including genital piercing) on the external genitalia, vagina or cervix in the last 14 days.~* Hysterectomy.~* Women using contraceptive IVRs because the study product is an IVR.~* Systemic use in the last 2 weeks or anticipated use during the study period of any of the following: corticosteroids, anticoagulants or ARVs.~* Plans to relocate away from the study site area during the period of study participation.~* Grade 1 or higher laboratory abnormality, as defined by the DAIDS Table for Grading the Severity of Adult and Pediatric AEs, Version 2.0, Nov 2014.~* At Screening or Enrollment, is pregnant (based on urine pregnancy test).~* In the last three months, diagnosed with or treated for any STI. Note: Women with a history of condylomata or genital herpes may be considered for eligibility as long as there are no lesions on exam. HSV 1 and 2 serologies will be obtained. Participants will be included regardless of the results of these serologies.~* Reproductive tract infection (RTI) or pelvic inflammatory disease (PID) requiring treatment per local guidelines in Kenya and Centers for Disease Control and Prevention (CDC) guidelines in the US at Screening or Enrollment.~Note: Otherwise eligible women diagnosed with symptomatic vulvovaginal candidiasis (VVC), symptomatic bacterial vaginosis (BV) or urinary tract infection (UTI) will be eligible if Visit 2 (Enrollment) is scheduled after all symptoms have resolved and at least two weeks after completing treatment. Women with recurrent VVC and symptomatic BV despite treatment will be offered another course of treatment and will not be eligible.~* Positive test for Trichomonas vaginalis, Neisseria gonorrhea or Chlamydia trachomatis at screening.~* Positive test for hepatitis B (defined as positive for hepatitis B surface antigen).~* Reactive serologic test for syphilis at screening (per local guidelines). Note: Women with a history of syphilis that was not acquired and/or treated within the past 3 months and that has been appropriately treated may be considered for eligibility.~* At Screening or Enrollment, has a clinically apparent Grade 1 or higher pelvic exam finding (observed by study clinician or designee) per the DAIDS Table for Grading the Severity of Adult and Pediatric AEs, Addendum 1, Female Genital Grading Table for Use in Microbicide Studies.~Note: Cervical friability bleeding associated with speculum insertion and/or specimen collection judged to be within the range of normal according to the clinical judgment of the PL/designee is considered expected non-menstrual bleeding and is not exclusionary.~- Pap result Grade 2 or higher according to the Female Genital Grading Table for Use in Microbicide Studies Addendum 1 to the DAIDS Table for Grading Adult and Pediatric AEs, Version 1.0, December 2004 (Clarification dated August 2009).~Note: Women 21 years of age or older with a documented normal result within the 12 months prior to enrollment need not have Pap smear during the screening period. Women with a Grade 1 abnormal Pap smear can be enrolled upon completion of the initial phase of evaluation if no current treatment is indicated (based on local standard of care for management of abnormal cervical cytology). Need for a repeat Pap within 6 months does not preclude enrollment prior to that result becoming available.~* At Screening, has severe pelvic relaxation such that either the vaginal walls or the uterine cervix descend beyond the vaginal introitus with Valsalva maneuver.~* Has any condition that, in the investigator's opinion, would preclude informed consent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives.

- Gender: FEMALE
- Minimum Age: 18 Years
- Maximum Age: 45 Years
- Healthy Volunteers: t

Study Arms:
- TDF IVR group (Type: EXPERIMENTAL): The Tenofovir Disoproxil Fumarate intravaginal ring (TDF-IVR) is a white (with clear segment), flexible torus-shaped device with an inner core which contains the experimental drug, TDF, and sodium chloride. The intravaginal ring is worn continuously for 28 days and replaced with new rings twice (every 28 days) for total of 84 days (3 months).~Participants will be stratified by site and will be randomized in a 3:1 ratio (TDF:Placebo).
- Placebo IVR group (Type: PLACEBO_COMPARATOR): The placebo intravaginal ring (IVR) is a clear, flexible torus-shaped device with an inner core which contains sodium chloride. The intravaginal ring is worn continuously for 28 days and replaced with new rings twice (every 28 days) for total of 84 days (3 months).~Participants will be stratified by site and will be randomized in a 3:1 ratio (TDF:Placebo).

Based on this trial design, predict the completion outcome and termination type (if applicable).
