The definition of vaccine by some authorities changes according to evidently non-medical requirements. I'm not making a point. This is an observation. https://www.citizensjournal.us/the-cdc-suddenly-changes-the-definition-of-vaccine-and-vaccination/ https://www.citizensjournal.us/the-cdc-suddenly-changes-the-...
