The 2000 Simpsonwood CDC conference (officially titled Scientific Review of Vaccine Safety Datalink Information) was a two-day meeting convened in June 2000 by the Centers for Disease Control and Prevention (CDC), held at the Simpsonwood Methodist retreat and conference center in Norcross, Georgia. The key event at the conference was the presentation of data from the Vaccine Safety Datalink examining the possibility of a link between the mercury compound thimerosol in vaccines and neurological problems in children who had received those vaccines.
