Just use your imagination how you would abuse mass vaccination and someone else likely has also thought of it as more than simply a thought experiment.

I read a brilliant SF book dealing with that to an extreme. Some Nazi Mengele type character had invented a toxin that only killed (always) those with Jewish DNA. There was an ingenious plot to put it into the water supply of the USA, Israel, Europe, etc. Of course it all worked out OK - but that day might well be coming.
