结论增加检测次数或选用进口试剂排除HIV感染意义有限，改进血液筛查手段实为提高血液安全性的首要途径。

Conclusion the significance of increasing detection times or using imported reagent for detection of HIV infection is limited and to improve techniques for blood screening is the first way of choice.

We did not yet have good methods for screening blood to look for HIV, we didn't have the ELISA technique that I--we talked about in section a few weeks ago and so there was a great concern that there might be other diseases that you'd be passing on from-- unknowingly from this subset of patients that you're isolating the vaccine from.

那时我们还没有一种好的方式,来从血液中筛查出HIV,也还没有ELISA技术,该技术我们在几周前的一个章节中谈到过,因此,那时仍存有,很大的担心,那就是你有可能,在不知情的情况下,被那些病人,感染上其它疾病,因为疫苗就是从他们身上提取出来的
