PrEP, a breakthrough medication since 2012, significantly reduces HIV transmission risk by 99% when taken correctly. Available in daily pills, long-acting injectables, and on-demand forms, it's safe for all, including pregnant individuals. Despite its effectiveness, only 25% of those who could benefit are prescribed it, with racial disparities in uptake. A new biannual injection, lenacapavir, nearing FDA approval, shows near 100% protection in trials. PEP, another HIV prevention method, is for emergency use within 72 hours of exposure.
