Sorry, never mind, the case of children's vaccines

The hysteria about mercury in childhood vaccines went on despite "reams of scientific studies," but the pressure of lawsuits forced pharmaceutical companies to change how they make vaccines. Now a new TV drama is continuing the crusade, but I found this interesting:

For the last decade some parents and advocates for autistic children have championed the theory that a mercury-based vaccine preservative called thimerosal, developed in the late 1920s and used in many childhood vaccines until about seven years ago, is a primary cause of autism in young children.

Autism often is diagnosed in children between their first and fourth years, during the time that many children begin receiving regular rounds of vaccinations.

But reams of scientific studies by the leading American health authorities have failed to establish a causal link between the preservative and autism. Since the preservative was largely removed from childhood vaccines in 2001, autism rates have not declined. . . .

And people wonder why the pharmaceutical is under siege.
