I think this is likely the correct answer.

I don't recall seeing a proven way to vax people through food tampering outside of sci-fi horror stories. This is probably more fear-mongering hoaxes to manipulate us and to get us to embarrass ourselves.

And the sad part is, it is working. The whole Great Awakening community more or less ate it all up hook, line, and sinker without even stop and thinking on how would all of this work. I am embarrassed that it even took this long for someone to stop and ask the question. Keep this up, and GAW will turn into a stupid and sad joke like PDW.
