You are incorrect regarding thimerosal in the Hepatitis B vaccine. There is NO mercury and no thimerosal in any HepB vaccine on the market. You're simply incorrect. The vaccines were removed with much fanfare over two years ago.
Keep up your tin hat though... it's real attractive (/smirk)
But not until there was an outcry from parents and others. Since it takes about two years for autism to present itself in the child (and sometimes 4 years to be diagnosed) it is possible that some children receiving Thimerosol have not been diagnosed yet. And were all of the vaccines removed from the stocks of pediatricians, hospitals, health departments? I know that they had a difficult time tracing the source of the batch of vaccine my grandson recieved. Finally it was determined that it did contain thimersorol, but it took a while to determine it.
Of course, we have no way of knowing whether this caused his condition. But we are not taking any chances with his little brother, either.
