ATLANTA—Moms Against Mercury (MAM) protested vaccine Wednesday at the Centers for Disease Control (CDC). According to the group's Web site, mercury-based thimerosal in vaccines can cause autism. The protest targeted the H1N1 vaccine.

Some MAM members wore hazmat suits to represent the idea that vaccines contain toxic chemicals. The use of suits provided by the group was approved by the Department of Homeland Security, but no American flags were allowed, said the group in a statement. The group discouraged violence, blocking entrances, or the use of bullhorns, but a Web site they link to calls doctors who recommend vaccination "liars." The related Web site speculates that the HINI virus has a "suspicious pedigree" and may have been released from a lab.

The CDC recommends that children, young people and some other groups get the H1N1 vaccination. Some of the vaccinations will contain thimerosal. "CDC is aware that the presence of the preservative thimerosal in vaccines and suggestions of a relationship to autism has raised concerns," according to a statement.

At the CDC, media contact Patricia Allen said the protesters "were here this morning. I didn't see them. I came in the back way."
