There is still thimerosal in some vaccines. Here is the CDC's list of thimerosal containing vaccines:
Illinois Vaccine Awareness Coalition
On July 5, 2005, the Food and Drug Administration released a list of vaccines with thimerosal (49.6 percent ethyl mercury). The following vaccines, still contain mercury as part of their manufacturing process or as a preservative.

Amounts range from .5 micrograms to 25 micrograms. Check the CDC's web site for exact amounts. Vaccines with .5 micrograms are usually described as "low dose mercury" vaccines. However, there has never been any safety testing on thimerosal, so no one knows how much mercury is enough to cause harm.
Lead, a less potent neurotoxin than mercury, is considered unsafe at any level.
