Attenuated Listeria monocytogenes vaccine strains have been administered intravenously (Le et al., Maciag et al.) and orally (Angelakopoulos et al., Johnson et al.) to humans. Here, one was given transcutaneously with cholera toxin adjuvant.
Eight healthy volunteers were studied (5 active, 3 placebo). Safety was assessed by physical exam and labs. Systemic immunological responses were measured by ELISA and IFN-gamma ELISpot.
4/5 active volunteers had cellular responses to listerial antigens. 5/5 active volunteers showed humoral responses to cholera toxin.
An attenuated L. monocytogenes vector was safely administered transcutaneously. Topical administration appeared at least as immunogenic as previously studied oral delivery.
减毒李斯特菌疫苗株已通过静脉内(Le 等人,Maciag 等人)和口服(Angelakopoulos 等人,Johnson 等人)途径施用于人类。在这里,用霍乱毒素佐剂经皮给予了一种疫苗。
对 8 名健康志愿者进行了研究(5 名活性,3 名安慰剂)。通过体检和实验室检查评估安全性。通过 ELISA 和 IFN-γ ELISpot 测量系统免疫反应。
4/5 名活性志愿者对李斯特菌抗原产生了细胞反应。5/5 名活性志愿者对霍乱毒素表现出体液反应。
经皮安全给予减毒李斯特菌载体。局部给药的免疫原性至少与先前研究的口服给药相当。
