Herpes simplex virus (HSV) is an alpha herpes virus, with two subtypes: HSV-1 and HSV-2. HSV is one of the most prevalent sexually transmitted infections. It is the cause of severe neonatal infections and a leading cause of infectious blindness in the Western world. As of 2016, 13.2% of the global population ages 15-49 were existing with HSV-2 infection and 66.6% with HSV-1. This high prevalence of disease and the fact that resistance to current therapies is on the rise makes it imperative to develop and discover new methods of HSV prevention and management. Among the arsenal of therapies/treatments for this virus has been the development of a prophylactic or therapeutic vaccine to prevent the complications of HSV reactivation. Our current understanding of the immune responses involved in latency and reactivation provides a unique challenge to the development of vaccines. There are no approved vaccines currently available for either prophylaxis or therapy. However, there are various promising candidates in the pre-clinical and clinical phases of study. Vaccines are being developed with two broad focuses: preventative and therapeutic, some with a dual use as both immunotherapeutic and prophylactic. Within this article, we will review the current guidelines for the treatment of herpes simplex infections, our understanding of the immunological pathways involved, and novel vaccine candidates in development.
单纯疱疹病毒(HSV)是一种甲型疱疹病毒,有两种亚型:HSV - 1和HSV - 2。HSV是最常见的性传播感染之一。它是严重新生儿感染的病因,也是西方世界感染性失明的主要原因。截至2016年,全球15 - 49岁人口中,13.2%感染了HSV - 2,66.6%感染了HSV - 1。这种疾病的高流行率以及对当前治疗方法的耐药性不断上升的事实,使得开发和发现新的HSV预防和管理方法势在必行。在针对这种病毒的一系列治疗方法中,开发预防性或治疗性疫苗以预防HSV再激活的并发症是其中之一。我们目前对潜伏和再激活过程中涉及的免疫反应的理解,给疫苗的开发带来了独特的挑战。目前尚无获批用于预防或治疗的疫苗。然而,在临床前和临床研究阶段有各种有前景的候选疫苗。正在开发的疫苗主要有两个重点:预防性和治疗性,有些具有免疫治疗和预防的双重用途。在本文中,我们将回顾单纯疱疹感染的当前治疗指南、我们对所涉及免疫途径的理解以及正在开发的新型候选疫苗。
