A quantitative ELISA for the detection of IgG antibodies in response to the Cuban vaccine against the human leptospirosis (vax-SPIRAL) was applied to 930 volunteers'sera, 483 immunized with vax-SPIRAL and 447 with a vaccine against hepatitis B. Samples were taken before beginning the study, 21 days after the second dose and a year later. A high seroprevalence of antibodies to the vaccine serovars was observed before beginning the study. The initial value of the response doubled at 21 days of the second dose in 45 % of the individuals. There were markedly significant differences (p=0,000000) between both groups. A similar response to the three leptospiral serovars was found. After the year the levels of antibodies decreased; however, 23.1% of the individuals were able to duplicate their level of antibodies regarding the initial moment, and the significant difference with the group that received the vaccine against hepatitis B still existed. The application of this Cuban immunogen amomg the main risk groups was recommended.
一种用于检测针对古巴人钩端螺旋体病疫苗(vax - SPIRAL)产生的IgG抗体的定量酶联免疫吸附测定(ELISA)应用于930名志愿者的血清,其中483人接种了vax - SPIRAL疫苗,447人接种了乙肝疫苗。在研究开始前、第二剂疫苗接种后21天以及一年后采集样本。在研究开始前观察到针对疫苗血清型的抗体具有较高的血清阳性率。45%的个体在第二剂疫苗接种21天时反应的初始值翻倍。两组之间存在显著差异(p = 0.000000)。发现对三种钩端螺旋体血清型有类似反应。一年后抗体水平下降;然而,23.1%的个体能够使抗体水平相对于初始时刻翻倍,并且与接种乙肝疫苗的组仍存在显著差异。建议在主要风险人群中应用这种古巴免疫原。
