As I often say 'language engineering precedes social engineering', but in this case maybe the reverse is true. People have been brainwashed their whole lives to believe that vaccines are 'safe and effective' (they're not) and so if you call something a 'vaccine' they'll line up and submit to it based on that false belief. They won't even look into that thing to see what it is,what's in it and what it does (even if you could trust what they say about it).
