I also think there is more to worry about than just the thimerisol. I think the viruses themselves damage the immune system. So while the thimerisol may have been setting up the MMR (and other viruses)to reek havok on the gut and immune system, the viruses may also be capable of damage in their own right. Time will tell once the thimerisol is completely off the shelf, its too bad some actual studies arent done...but of course if they wanted the answer the studies would be done. And not just statistical "paper" studies...
