We read with interest the Review by Omar Galárraga and Sandra Sosa-Rubí that paradoxically appeared in The Lancet HIV at the same time as the California Senate Bill 159, which authorised dispensation of pre-exposure prophylaxis (PrEP) without prescription. We agree that incentives for PrEP should be urgently studied.

我们感兴趣地阅读了OmarGalárraga和SandraSosa-Rubí撰写的《评论》，它与《加利福尼亚州参议院第159号法案》同时出现在《柳叶刀》 HIV上，该法案授权无需处方即可免除暴露前预防（PrEP）。我们同意应紧急研究对PrEP的激励措施。
