I don't know about this "Thermisol," however.
Unfortunately, since researchers now think there may be a number of environmental factors that are increasing the risk for autism, removing only one factor while the others are still increasing wouldn't give a clear result. For example, during the same period of time since mercury has been removed from vaccines, the use of Roundup and other glyphosates has been increasing; and they have also been linked to an increased risk of autism symptoms.
That is a serious problem in epidemiological research -- when there are a combination of factors that could be causing harm, how do you untangle the effects of each? But we do KNOW that babies were receiving, in their combination of several vaccines, more thimerosal than had been approved by the FDA. This is undisputed. And it wasn't necessary to include thimerosal in single-use vials. So that was the decision that was made.
