Shigella spp. represent the second most common etiologic pathogen causing childhood diarrhea in developing countries. There are no licensed Shigella vaccines, and progress for such vaccines has been limited. In this issue of Clinical and Vaccine Immunology, Riddle and colleagues (M. S. Riddle, R. W. Kaminski, C. Di Paolo, C. K. Porter, R. L. Gutierrez, et al., Clin Vaccine Immunol 23:908-917, 2016, http://dx.doi.org/10.1128/CVI.00224-16) report results from a phase I study of a parenterally administered monovalent O-polysaccharide "bioconjugate" directed against Shigella flexneri 2a. Ultimately, the goal is to develop a broad-spectrum Shigella vaccine to address this public health concern. A parenteral Shigella vaccine capable of eliciting protection in children of developing countries would be an important tool to reach this goal.
志贺氏菌属是发展中国家引起儿童腹泻的第二大常见病原体。目前尚无已获许可的志贺氏菌疫苗,此类疫苗的研发进展有限。在本期《临床与疫苗免疫学》中,里德尔及其同事(M.S. 里德尔、R.W. 卡明斯基、C. 迪保罗、C.K. 波特、R.L. 古铁雷斯等人,《临床与疫苗免疫学》23:908 - 917,2016年,http://dx.doi.org/10.1128/CVI.00224 - 16)报告了一项针对弗氏志贺菌2a的单剂量注射用单价O - 多糖“生物偶联物”的I期研究结果。最终目标是研发一种广谱志贺氏菌疫苗,以解决这一公共卫生问题。一种能够在发展中国家儿童中引发保护作用的注射用志贺氏菌疫苗将是实现这一目标的重要工具。
