• Researchers have identified a specific signature of vaginal bacteria and inflammatory proteins associated with elevated HIV infection risk in women.
• The study pinpointed 14 bacterial taxa and six inflammatory proteins, where the presence of all markers significantly increased HIV risk.
• Lactobacillus crispatus was identified as a bacterial species associated with protection against HIV infection, offering potential preventative strategies.
• Findings suggest potential for targeted interventions, such as antibiotics or probiotics, to modify the vaginal microbiome and reduce HIV risk.
