The 15 ug/L figure was just the first one I found—the study actually noted that most others have found lower (5-10 ug/L) levels in children.
Instead of working backwards, why not just compare blood AL levels in matched vaccinated and unvaccinated children? Different countries have different vaccination schedules and so on. I’m not digging further because I should be doing other stuff, but it’s a good lead.
I couldn’t find any reference Al levels for childrens’ brains.
1.67mg/g of Aluminum in a one-year-old’s brain doesn’t pass the sanity check. I think the above chart has a typo—that should be ug/g, not mg/g. Otherwise the mice would be very dead! Also, normal Al levels in the brain are around 1 ug/g, a mouse has a brain mass massing 0.4g (dry mass ~0.3g), and 1mg/g would imply ~0.3 mg of Al, far more than injected in the first place.
in premature infants fed orally, mean AL level is 5 mcg/L, SD of 3
another study of very young infants 4 − 5 mcg/L, SD of <1
It seems sensible to estimate that if 5 mcg/L is normal for newborns, and normal for older children, that it should be normal at age 1 as well.
I also found another study in China, which cited a geometric mean of >50 mcg/L. I guess either pollution or poor measurement equipment can totally wreck things.
A couple of things:

whoops, fixed my units. got too used to seeing it written in mcg/g!
some findings of blood levels
Paper from 2011 titled:
Wide variation in reference values for aluminum levels in children
This paper is from 1992:
cites two studies:
in premature infants fed orally,
mean AL level is 5 mcg/L, SD of 3
another study of very young infants
4 − 5 mcg/L, SD of <1
It seems sensible to estimate that if 5 mcg/L is normal for newborns, and normal for older children, that it should be normal at age 1 as well.
I also found another study in China, which cited a geometric mean of >50 mcg/L. I guess either pollution or poor measurement equipment can totally wreck things.
