This study looks at how well doxycycline (a type of antibiotic) can reach certain body tissues to help protect against HIV and sexually transmitted infections (STIs). Researchers hope to find a way to use a single dose of doxycycline along with other medicines to prevent these infections. The study involves healthy men and women who aren't using gender-changing treatments. Participants will have to give samples like blood, urine, and tissue from the rectum or vagina. The study lasts about eight weeks, during which doxycycline is taken by mouth.
Key Points:
- Study duration is approximately 8 weeks.
- Participants will provide samples and take doxycycline.
- Recruitment through various community and online platforms.
