Study of the serological responses in man to typhoid vaccines tested in several WHO-sponsored controlled field trials in British Guiana, Poland and Yugoslavia has not indicated any correlation between the level of Vi and O antibodies elicited and the effectiveness of the vaccines. Instead, the more effective vaccines have elicited significantly greater H-antibody responses; but a variety of factors suggests that it may in fact not be the antibody that confers immunity to the disease. The phagocytic test does not appear promising as a technique for determining the effectiveness of a typhoid vaccine, but passive protection of the chick-embryo may warrant further investigation.
在英属圭亚那、波兰和南斯拉夫进行的多项由世界卫生组织赞助的对照现场试验中,对人体针对伤寒疫苗的血清学反应进行的研究表明,所引发的Vi抗体和O抗体水平与疫苗的有效性之间没有任何关联。相反,更有效的疫苗引发了显著更强的H抗体反应;但多种因素表明,实际上赋予疾病免疫力的可能并非抗体。吞噬试验作为一种确定伤寒疫苗有效性的技术似乎前景不佳,但鸡胚的被动保护可能值得进一步研究。
