The smallest newborns can be less than half the weight
of the largest newborns and this difference can continue
until approximately 6 months of age. Guidelines should
prevent potential harm from mercury exposure in this most
vulnerable population, as pointed out by Kathryn R.
Mahaffey, PhD, from the EPA. "If we take the weights of
these children, and assume that they are receiving
thimerosal-containing vaccines for each of the recommended
vaccines by age, the following figure shows the dose of
mercury in micrograms per kilogram that they would receive
on the day vaccine is administered."
