So now it is well understood that both mercury compounds uptake as inorganic mercury in the brain, which can last several years to several decades. What does that mean regarding chronic brain inflammation, which is well understood and demonstrated in individuals with autism (evidence)? Inorganic mercury in the brain is associated with microglia activation, which creates inflammation and neural damage. This current study along with all of the supportive data demonstrates the need to remove thimerosal from all vaccines administered not only in the United States but for the rest of the world. Further, it should be noted that thimerosal is but one avenue leading to chronic brain inflammation and autism but it is an obvious piece to the puzzle.
