RALEIGH, N.C. — A group of mothers who blame mercury in vaccines for their children's autism score a win in the state Legislature.

A bill restricting the amount of Thimerosal allowed in vaccines cleared the health committee.

There is an ongoing debate on whether the mercury-based preservative can be linked to developmental problems.

The bill would also restrict Thimerosal in flu shots for children and pregnant women. The legislation now moves to another committee.
