AOA has a piece on Dr. Sears Mothering article. He assumed aluminum had been safety tested before putting in vaccines.
Never assume that just because a toxin is being injected into babies at high levels, that it has been safety tested.
It appears that we have removed mercury, an adjuvant that causes autoimmune disorders, mitochondrial disorders and kills brain cells, and we have replaced it with aluminum, an adjuvant that causes autoimmune disorders, mitochondrial disorders and kills brain cells.
I should add that Heath Advocacy in the Public Interest randomly tested vaccines and found that one had 1,117 mcg of aluminum in it. (their site seems to be down right now)
UPDATE: I stand corrected by Quantumerik and Boyd Haley. I sent the question to Dr. Haley and this was his response:
"Thimerosal is not an adjuvant, it does not enhance the immune response to an antigen as does aluminum. It is only added as a preservative. The pharmaceutical companies and their supporters would like for thimerosal to be an adjuvant, then they could not be sued for adulterating their vaccines and all costs would have to fall on the government programs for vaccine injury. -boyd"
