I guess they could (will?) argue that there never was any COVID virus, as it was all a mislabeled or misidentified or non-existent disease. This would make the only source of those dangerous spike proteins the mRNA vaccines themselves. Which should have them arguing that the other vaccines, lacking mRNA, were not part of the problem but I doubt they parse that finely.

Sadly, I don't really think this is satire as much as a reasonable prediction of how things will be rationalized if they bother to change their initial statement at all.
