"The amount found in the blood was about one-tenth of that predicted in that the late 1990s and the length of time it stays in the blood is one-tenth of that predicted," Pichichero said.
Mercury levels also were measured in the babies' stools and urine. In the stool samples, the levels were highest after vaccination and also fell, but more slowly than blood levels. There was no significant amount of mercury in the urine.
The authors could not determine what happened to all the mercury after it left the blood. All the infants gave samples twice: before vaccination and at one other time, ranging from 12 hours later to 30 days.

Somehow, I bet that they will find all that mercury in the autopsy... somewhere, perhaps in the liver... maybe?
