| |      | Dr. Halsey's presentation at the National Vaccine Advisory Committee Workshop on Thimerosal and Vaccines held in Bethesda, Maryland on August 11-12, 1999. | Slide 9 of 26 | Slide Notes: There are numerous factors associated with mercury toxicity, as noted on the slide. All children are not created equal with regard to their risk from exposure to mercury. We cannot control many of these factors, but we can have some control over the age and weight of children at the time they are exposed to mercury in vaccines. | |
