Summary
The first study of doxycycline postexposure prophylaxis for cisgender women did not reduce incident STIs likely due to low use of doxycycline. Researchers will conduct a pilot study of once-weekly doxyxycline to prevent bacterial STIs among Kenyan cisgender women using PrEP for HIV prevention.
