A. The meningococcal type B (4CMenB) vaccine significantly reduced the rate of gonorrhea infections among men who have sex with men (MSM)

B. Despite an increase in sexual risk among MSM and transgender women newly starting doxycycline postexposure prophylaxis (doxy-PEP), bacterial STI rates fell by approximately half

C. Doxycycline was present in the majority of hair samples collected among women in the dPEP-KE (Doxycycline PEP for Prevention of Sexually Transmitted Infections Among Kenyan Women Using HIV PrEP) study, suggesting that biologic factors explain the lack of doxy-PEP efficacy in women

D. In the year after the implementation of doxy-PEP guidelines in San Francisco, rates of chlamydia, syphilis, and gonorrhea in MSM and transgender women fell by half
