Summary

This study tested whether taking an antibiotic (doxycycline) after sex or getting a meningitis vaccine (Bexsero) could prevent sexually transmitted infections (STIs) like chlamydia, syphilis, and gonorrhea. It involved 556 men who have sex with men and were already using HIV PrEP. The goal was to find new ways to reduce STIs in this group.
