People blame vaccines but it's antibiotics. The incidence of vaccines and antibiotics being given at the same time is high. Antibiotics, apart from allowing carcinogenic bacteria to grow, also allow bacteria that release neurotoxins to thrive, causing autism.

You have to get the good shit from a health food store, in the refrigerated section. This shit cured my wheat allergy that I developed after really bad strep throat.
