In a recent government meeting, discussions centered around concerns regarding mercury exposure from vaccines, particularly those containing thimerosal, a preservative that is 50% mercury by weight. A public health official from Georgia recounted receiving a notice about the precautionary delay of the hepatitis B birth dose due to mercury exposure concerns, despite assurances that the exposure levels were low and posed no harm.

The official expressed alarm upon reviewing her son's vaccine records, discovering that he had received multiple vaccines containing thimerosal. She highlighted that at two months old, her son had an allowable mercury exposure of 0.5 micrograms, yet he received 62.5 micrograms—125 times the EPA's recommended limit. This raised significant red flags for her, especially as she and her husband were searching for explanations for their son's developmental regression.

To investigate further, she sent a lock of her son's hair to a toxicology lab, which revealed mercury levels five times above the allowable exposure, alongside elevated aluminum levels. She noted that the symptoms her son exhibited—loss of speech and eye contact—aligned with findings in mercury toxicity literature.

The meeting also featured insights from Dr. Boyd Haley, a prominent authority on mercury toxicity. He shared findings from experiments demonstrating that mercury could kill up to 50% of neuronal cells in brain tissue, while aluminum was less toxic on its own but lethal when combined with mercury, leading to 100% cell death. Dr. Haley's research underscored the synergistic effects of mercury and aluminum, amplifying their toxicity when present together.

These discussions have reignited concerns among parents and health officials about the safety of vaccines containing thimerosal, prompting calls for further investigation into the potential health impacts of mercury exposure in children.
