There is much more interesting things in that paper.
First:
Authors fully describe replication and isolation of adenovirus of interest, finally getting electron microscopy image of purified sample with many identical objects without anything else.
How strange - you see, virus isolation is a routine procedure. To isolate virus of interest and get good EM image of identical objects just to find out proteins layout on the virus shell is not a problem at all. It is even not a goal of their research, just a intermediate step on a way to obtain necessary data for the study. It is a routine. Usual procedure of real virus isolation.
But still no one did that for SARS-CoV-2. :)
Second:
They study pure, unmodified adenovirus, not modified one from vaccine. Seems that even big international group of scientists from different institutes and universities was not able to obtain modified adenovirus version from vaccine. Or was not allowed to study it. They have a computer with 800Gb RAM and easily get pure adenovirus culture to replicate, but they can't get their hands on few vials of vaccine.
