Question

Quizplus · Accepted Answer

While the causes of autism spectrum disorders are currently unknown, research does not support exposure to mercury as a primary cause. However, some controversy exists around the use of thimerosal, a mercury-containing preservative, in vaccines and its potential role in the development of autism. The overwhelming scientific consensus is that vaccines (including those containing thimerosal) do not cause autism.
