This research involved adding thimerosal to vaccines, injecting them into monkeys, then running tests to see what happens There are numerous problems with this research however:

• There is a lot of noise in the data, making any useful reading difficult at best
• There is no data for before This means comparisons between before injection and after injection are impossible
• The vaccines used were not designed to contain thimerosal It is therefore difficult to predict any chemical reactions which may have occurred as a result of adding it to the vaccine
• Some of the results shown in this research contradict with other similar research, lending further doubt to this research
• By referring to thimerosal as 50% mercury by weight, the author(s) demonstrate either a complete understanding of chemistry and its applications to toxicity, or a bias in their reasoning

So, this research does not demonstrate vaccines cause autism At best it can provide information about the "rate at which different forms of mercury are removed from a primate’s brain and bloodstream"
