It makes me feel better that other people agree with me on the need of vaccines. But my question was slightly different, I'll try writing it back in a clearer way. If the State obliges you to vaccine in order to attend schools/work/etc, (unless you may not due to personal and specific circumstances), how would you react? You will say: "It is absolutely necessary to vaccine, so it isn't a problem" or "No, the State has no right to decide of my personal health".
For the sake of clarity, for me it isn't a problem, as quality and length of life had sharply improved after vaccines against polio and other diseases were developed. I personally think that vaccines are the best weapons against some diseases that may not be very dangerous in most of the cases, but that in other situations, (probably rare, but still with a chance different from zero), may have a bad outcome. There's no scientific evidence that vaccines may cause side-effects, and, from my knowledge, for the very rare people who suffered from them, it was essentially due to their specific physical condition. Obviously, I expect in return mainly three things: that vaccines are given free, that severe quality control is made for their production and last but not least, that if may happen that, by chance or not, vaccines may result side-effects on somebody, the State will take care of them.
