Any claims made about the effects of a substance on a body are readily verifiable, hence all claims made about the efficacy or toxicity of an intervention are based on studies that have been duplicated and put to the scrutiny of experts in the field. The data obtained is available to anyone who cares to scrutinize it. The conclusions drawn from the data are not opinions, they are based on observable, measurable and duplicatable studies.

As for the statement "Note what happens when you get a vaccination. Your body generally reacts to the vaccination with swelling, redness, soreness, and other signs of strong bodily reactions to toxicity in the place where you were vaccinated." The signs you claim to be evidence of toxicity are signs of the efficacy of the vaccination. This is, in fact, evidence that the body's immune system is functioning as it is supposed to and is mounting an immune response to the antigen being presented which will result in the production of protective antibodies against that substance.
