In fact, several of the studies found that children who received vaccines with thimerosal were less likely to develop autism.
Clearly, something other than thimerosal is to blame for this troubling trend.
Thimerosal was dropped as a preservative in MMR vaccines in 1999, but since then autism rates have skyrocketed.
This was enough for all the major medical and health associations to announce that thimerosal had no connection to autism.
