There's some serious problems with these slides and claims.

I don't disagree with the core principle of these claims, but the reasoning and evidence is very shaky at frequent times. The language is overly informal and not detailed enough at times, and these guys often quote themselves as sources. Not a good look without detailed evidence to go along with it (which, again, is often lacking).

There's a lot of good information in here but you have to be careful. I don't understand why they're choosing to present these claims in such a fashion. There's plenty of perfectly valid evidence here (and elsewhere) against the clot shots but it's just presented in such a poor way that it weakens their core argument.
