You seem pretty confident in your belief that vaccines are incapable of harm, and that vaccines have no credible association with autism spectrum disorders.
I happen to have done a reasonable amount of independent investigation into this subject. I discovered things like this (just one example):
Many vaccines, at the time they are injected, contain non-trivial amounts of Triton X-100, Octoxynol, Sodium Deoxycholate, and/or Sodium Taurodeoxycholate. These chemicals are cytotoxic — they cause cells to leak or explode by weakening their walls. This catastrophically mimics the membrane attack complex (MAC). The MAC is regulated by proteins to target foreign cells and avoid self-cells, respond to signals calling off the attack, and overall is integrated into complex (and sensitive) signaling and feedback relationships. But these vaccine chemicals are unregulated within the body, hit cells at random, continuously destroy cells, and disrupt signaling/feedback relationships. This can result in demyelination, neuropathy, dysferlinopathy, beta-amyloid growth, reperfusion injury, myasthenia gravis, and brain swelling. The research for this is available in PubMed and Toxnet (for starters), and it has nothing to do with Wakefield. If you need help finding citations I can walk you through it.
ASDs are defined in the DSM by a collection of behavioral symptoms. If you have the symptoms, you can be diagnosed with an ASD. Consequently, anything (in fact, everything) that causes those symptoms is by definition a cause of the ASD. Our world is swimming in chemicals demonstrated to cause physiological problems which in turn produce the behavioral problems. Are vaccines the ONLY source of exposure to such chemicals? Of course not. But to defend vaccines as universally safe is to remain misinformed.
