Well said!
For me, it comes down to the use of force in that vaccinations have become increasingly compulsory, as you pointed out. Having to force vaccines on any population seems to imply evidence of their lack-luster utility.
If vaccines were as effective as advertised, a mandate wouldn't be required. People would line up and pay the price willingly. Research into the failings of vaccines wouldn't be so profitable if there weren't so many.
Making vaccinations optional is the best policy for all parties concerned. It will promote more vigorous research into vaccines as well as alternatives, because those options will have to prove themselves to consumers. If you can produce a vaccine that convinces an "anti-vaxer" of its utility, you've got a real winner on your hands.
Good ideas don't require force to be adopted.
Mandatory vaccination violates the Nuremberg code, being medical procedures performed without informed consent. It is in the very first line of the code.
