They don’t work that way this is BS
use common sense ... IF a “digestible vaccine” was possible, wouldn’t they be using it already?
nobody likes needles, a digestible vaccine would be faster, cheaper, more appealing to the public ... every argument is in favor of it!
so the fact that they DON’T use that now, tells us that there’s no such thing
more paranoid fear-mongering (like we haven’t had enough already)
