This is a closeup of the AZ vaccine, straight out of the bottle. The two big blobs near the bottom are adenovirus particles. All the other crap is probably not supposed to be there and may be contributing to VITT. The black dots are anti-adenovirus antibodies. This shows us ...

... that the debris contains among other things, smashed up adenovirus particles. The text says, "These structures may be viral proteins or nucleic acids or HEK-
293 T-Rex proteins from the cell culture used for virus propagation". This picture is from the supplement linked in...

It's also notable just how much other junk they found in the vaccine. Between 43% and 60% of the total protein...
