So, it appears that the vaccines are loaded with all kinds of stuff: sharp metal structures, chip-like rectangles, moving aeroplane-like structures etc. To me the most scary thing – and I haven't even watched it all – were these long ropes/lianas/pearl bands that apparently slowly grow/develope after the vaccine warms up (makes you again wonder about the requirement of freezing temperature), and one of the researchers commented that they look similar to 'Morgellon's'. And it looks like these things grow to some kind of complex network, or something. And all of these findings are apparently confirmed by many different researchers.
It could also speak of a very poor purification level of the vaccines. That they didn't bother to filter them properly. That is without any additional sinister reasons for these foreign objects to be present.
I found this Twitter post (unless it was already shared), where you can see a lot of pictures, explaining the found abnormalities. Just click on the tweet and see the replies. One of the pics says: "Foreign bodies, contaminants, adjuvants in the vaccine. Microscopic examination of particles of unknown nature." So yeah, it seems like it could be a combination of various garbage, including a more sinister components.
This person also post a lot of other very interesting and concerning papers. You can also find all the info on his Telegram account.
