For a vaccine to get from phase I to phase III trials in just ten months, as rVSV-ZEBOV did, was unheard of at the time—a startling example of what urgency and organisation can do.

请问大神：比如这句句子介词+名词短语开头和只是名词开头，意思上有什么区别吗？比如这句我改成： A vaccine to get from phase I to phase III trials in just ten months, as rVSV-ZEBOV did, was unheard of at the time... 可以吗？为什么要加个for呢？有什么区别吗？

应该就是“For a vaccine to get from phase I to phase III trials in just ten months”，介词短语（词串）整体作主语。这种情况不太常见，怕是有一定教育背景的母语人士才会（经常）使用。对于这类“”非经典语法现象”，我们作为外语学习者，大概率是给它们安置一个能够自圆其说、看似较为合理的解释。以上完全是个人浅薄之见，权当抛砖引玉。

抱歉，引用的材料还是简单了些~ @ mxh3698 道友的解释，我表示认同，还原成一种“比较符合经典”的句子；至于加上介词 for，我个人的解读是，从翻译这个角度去考量。For a vaccine ..., was unheard of at the time 对于十个月内便能搞定三期疫苗实验（这种事情、情况等），真是闻所未闻。当然，我也一直以为，母语人士写出来的句子，多数情况会是更加地道和简洁，少数情况只有作者自己本人最为清楚（说不定是一种文字的显摆）。

For is needed here.

Or you can say, "it's unheard-of that a vaccine can go from Phase I to Phase II in just ten months".
Or
A vaccine going from .. to .. in ten months is unheard of.

我现在感觉是不定式做主语，to get from phrase I to phrase III... for a vaccine…

I am no expert in grammar. All the grammar terms make my head spin.

But I do know what's proper English. :P That's what matters in the end, right?
