So it can test for all serotypes of dengue and Zika simultaneously.”

所以它可以同时测试登革热和寨卡病毒的血清型。

So this would be one shot, with all 50 of the most common cold serotypes in it. It’s sort of a brute force approach.

所以这将是一次注射，其中包含所有 50 种最常见的感冒血清型。这是一种蛮力方法。

The problem is, at the time that this is all known in the 1980s, vaccine technology could only fit in a few serotypes per injection, without causing an enormous immune response.

问题是， 在 1980 年代这一切都为人所知的时候，疫苗技术每次注射只能适应几种血清型，而不会引起巨大的免疫反应。
