Today an argentinean page dedicated to raising science awareness, skepticism if you will, posted in Facebook that vaccines should be always mandatory. I wanted to state my disagreement but decided not to, because I didn't want to be a useful fool to pseudoscience, which is almost omnipresent in Argentina, and because I prefer to keep a low profile online.
I do believe that the scientific knowledge on vaccination is enough to say they're safe and effective, but you're absolutely right about it being a violation of self-ownership.
To be honest, I think said violation is a neccesary evil, but it's still a violation.
There are superior technologies available to those who can find their way out of this industry generated cul-de-sac. Mandatory vaccination is not only a violation of self-ownership. It is a war crime under the Nuremberg code. It says it in the very first line. Evil is never necessary.
