[ref. Bishop NJ, Morley R, Day JP, Lucas A aluminum neurotoxicity in preterm infants receiving intravenous-feeding solutions. N. Eng. J Med 1997;336:1557-1561.]
The FDA (Food and Drug Administration) has had a ruling in place for the past decade not to exceed 5 micrograms/Kg/day of parenteral aluminum.
Parenteral means IV or IM (injected).
The CDC continues to ignore this data and ruling calling for the injection of 250 micrograms of aluminum to all newborns born in the USA which is more than 10X (1000%) of the maximum allowable dose of aluminum injected with the Hepatitis B vaccine.
