This study looks at the outcome of Hepatitis B vaccination in prematures and term controls, testing the hypothesis that the T cell activation response to staph endotoxin B will predict the titer of antibody after 9 months. Cord blood is obtained at birth from prematures and a further four samples have been accrued in the past year. Permission to test the response, and to measure the antibody response to Hepatitis B is obtained at follow up. The total number of subjects being followed is currently 36, and the study will be closed to new entrants at this point.

这项研究着眼于丙型肝炎疫苗接种在前期和术语控制中的结果，检验了以下假设：T细胞激活对葡萄球菌内毒素B的激活反应将预测9个月后抗体的滴度。 脐带血是在出生时从前期出生的，在过去的一年中，另外四个样本被累积了。 随访时，获得了测试反应并测量对丙型肝炎的抗体反应的许可。 目前，遵循的受试者总数为36，这项研究将在这一点上关闭新进入者。
