Whichever anti-vaccine theory they may believe, whether it is about MMR, thimerosal, or something else, vaccines still don’t cause autism.
Dr. Viera Scheibner is a micropaleontologist who thinks that vaccines do not work, that vaccines are bad, and that getting vaccine preventable diseases, like pertussis and measles, is good for you.
Stephanie Seneff is a computer scientist from MIT who thinks that exposure to glyphosphate is causing everything from autism and Alzeimers to peanut allergies and Celiac disease. Interestingly, she had another theory that all of these things were caused by low fat diets and vitamin D deficiency before she got obsessed with glyphosate.
Although included in some vaccine package inserts, none actually claim that vaccines cause SIDS or autism.
