Doxycycline-PEP — novel and promising but needs monitoring

Sexually transmitted infections (STIs) remain public health concerns. Doxycycline post-exposure prophylaxis to prevent STIs is a novel promising intervention, which in a new study caused an 65% reduction in incident STIs. However, long-term effects on STI prevalence, microbiomes and antimicrobial resistance among STI pathogens, non-STI pathogens and commensals need to be monitored.
