利什曼原虫寄生虫会引起各种离散的临床疾病,这些临床疾病在其特定的沙蝇载体维持传播的地区。临床和实验室研究表明,已经提出了预防利什曼病和各种疫苗候选物的免疫潜力。不幸的是,多个因素排除了一些以上的利什曼原虫,将疫苗靶向临床试验。在Covid-19的背景下,RNA疫苗最近成熟到有执照的产品中,表明更广泛使用该技术的可能性。在此,我们讨论了RNA技术提供的潜在好处,以解决利什曼菌疫苗遇到的瓶颈的方法。此外,我们概述了各种策略,这些策略可用于更有效地评估利什曼尼亚疫苗功效,包括受控的人类感染模型和在治疗环境中的初始使用,这些策略可以优先考虑候选人,然后在更大,更长且更复杂的现场试验中评估之前。
Leishmania parasites cause a variety of discrete clinical diseases that present in regions where their specific sand fly vectors sustain transmission. Clinical and laboratory research indicate the potential of immunization to prevent leishmaniasis and a wide array of vaccine candidates have been proposed. Unfortunately, multiple factors have precluded advancement of more than a few Leishmania targeting vaccines to clinical trial. The recent maturation of RNA vaccines into licensed products in the context of COVID-19 indicates the likelihood of broader use of the technology. Herein, we discuss the potential benefits provided by RNA technology as an approach to address the bottlenecks encountered for Leishmania vaccines. Further, we outline a variety of strategies that could be used to more efficiently evaluate Leishmania vaccine efficacy, including controlled human infection models and initial use in a therapeutic setting, that could prioritize candidates before evaluation in larger, longer and more complicated field trials.
