Charleston JS, Bolender RP, Mottet NK, Body RL, Vahter ME, Burbacher TM, Increases in the number of reactive glia in the visual cortex of Macaca fascicularis following subclinical long-term methyl mercury exposure. Toxicol Appl Pharmacol. 1994 Dec; 129(2):196-206.
This is a different study from the 1996 study referenced in the previous post, but it is drawn from the same research: the same group of monkeys.
- The study is on methyl mercury, not ethyl mercury, which is what is in thimerosal.
- The monkeys were exposed to very high doses (50 micrograms Hg/kg body wt/day) every day for months.
- There is no research linking increased reactive glia in the visual cortex to autism.
Does this paper "demonstrate that vaccines can cause autism"? No. This study demonstrates that monkeys given high doses of methyl mercury have specific changes to one type of cell. The paper does not support the vaccine-causation hypothesis.
