No Link Between Thimerosal and Autism

New thimerosal study, altogether now...

...there's still no link.

Neuropsychological Performance 10 Years After Immunization in Infancy With Thimerosal-Containing Vaccines’ is a new study from Italy.

70% of the invited subjects participated in the neuropsychological
assessment (N = 1403). Among the 24 neuropsychological outcomes that
were evaluated, only 2 were significantly associated with thimerosal
exposure. Girls with higher thimerosal intake had lower mean scores in
the finger-tapping test with the dominant hand and in the Boston Naming

And here’s the conclusion from the penultimate page of the paper (excluding references):

study conducted to date has been able to provide conclusive evidence of
an effect of thimerosal on neuropsychological development. Final
judgments regarding this association must rely on the entire body of
results from studies conducted in different settings and with different
levels of validity and on the coherence of results. The lack of
consistency among the results of our study and other available studies
suggests that an association between thimerosal exposure through
vaccination in infancy and neuropsychological deficits is unlikely or
clinically negligible. Additional data from populations with wider
ranges of exposure to thimerosal and additional neuropsychological assessments at
older ages may help to clarify the issue of potential associations
between thimerosal and neurodevelopmental outcomes.

Oh, and for the conspiracy theorists:

The authors have indicated they have no financial relationships relevant to this article to disclose.

not an epidemiologist so I’m not going to attempt to go through the
nuts and bolts of this paper. Hopefully those who have more expertise
can go through yet again why this shows that thimerosal in vaccines
seems to be about as dangerous as the average housefly. I can’t imagine
they really want to. God knows I don’t. But the stupidniks will no
doubt need the finer points hammered home again.

Can you sense I’m getting bored with this yet?
