Re: taking the trouble to understand the study

77203 said: "There are vaccines after 7th month, many more then before 7th month."

The study was specifically set up to look at early exposures to thimerosal-containing vaccines. That's the period in which some claim there is a particular susceptibility to this preservative. The study did not find evidence of preservative-related neuropsychological problems.

"On this planet and especially among educated people, when it comes to vaccines, the number one concern is the incredible rise in autism spectrum disorders among vaccinated children. If they didn't assess that, then they cannot claim they assessed anything of significance in regards to mercury in vaccines."

They assessed many measures of brain function. There are numerous other studies that have specifically looked at autism, and have also not found an association with thimerosal or with vaccines in general.

"Is "a few" (significant associations with exposure to mercury) a new number used in manipulating data? Certainly appears so."

You apparently did not read the conclusions of the study. Both positive and negative associations with thimerosal were noted:

"Higher prenatal mercury exposure was associated with better performance on one measure of language and poorer performance on one measure of attention and executive functioning. Increasing levels of mercury exposure from birth to 7 months were associated with better performance on one measure of fine motor coordination and on one measure of attention and executive functioning. Increasing mercury exposure from birth to 28 days was associated with poorer performance on one measure of speech articulation and better performance on one measure of fine motor coordination."

The bottom line is that these "associations" were small, were both positive and negative, and overall not significant.

"(this study) took into account only mercury (as if that's the only vax ingredient with toxic properties)"

Mercury (the thimerosal preservative that used to be routinely used in vaccines) is the ingredient that antivaxers have been harping on as an alleged cause of brain damage in vaccinated children. So naturally it's been the subject of this and many other studies refuting the theory. As the mercury theory has repeatedly been debunked, antivaxers then begin claiming (similarly without evidence) that various other components of vaccines are "toxic". This strategy is similarly doomed to failure.

For antivaxers, it's never really been about the mercury, but about vaccines themselves, for which they bear an irrational hatred. Tweet
