And when there is a chance of adverse outcome from vaccines, no matter how small it is (and there is one, says so right on the documentation that comes with the vaccine), you should be able to make the choice of whether you want the vaccine or not.
Then become a hermit. Otherwise you are putting other people at risk.
If you are concerned about the miniscule risk that vaccines might pose (and all the fear-mongering about mercury, autism, etc. is bogus) then you must not subject yourself to any medical procedure. Vaccinations have a safer record than just about any other medical procedure. Even getting your teeth cleaned has risks.
