In the first article, you said, "an untested (yes, untested) vaccine". Now you're saying "only a subset of the typical tests". These two statements contradict each other.

The normal process for testing vaccines takes about a decade. We didn't have a decade to wait before dealing with this immediate emergency that has killed millions of people.

I have read the research, by the way. If you have really read the research, then you should easily be able to answer this question: "In your own words, how does science claim that COVID-19 get past the human immune system?"
