This blog post claims that vaccines given to infants contain less aluminum than is typically ingested from milk - especially formula milk. A more prestigious source of this claim is the Children's Hospital of Philadelphia. They state:

While infants receive about 4.4 milligrams of aluminum in the first six months of life from vaccines, they receive more than that in their diet. Breast-fed infants ingest about 7 milligrams, formula-fed infants ingest about 38 milligrams, and infants who are fed soy formula ingest almost 117 milligrams of aluminum during the first six months of life.

However, this paper in Pediatric Nephrology says that the average infant on formula absorbs .0008 mg Al per kg of body weight per day (the breast-fed infant receives significantly less - on the order of 1/10). I can't resolve how this matches the claims above.

Is it true that more aluminum is ingested in the first six months of formula-drinking infant than is injected or ingested by the scheduled vaccines?

    Whatever the calculations about the amount of aluminium (aluminum for US readers), you also have to take into account the chemistry of the compounds: some are essentially completely inert and will simply pass through the body (eg the hydroxide in antacids).

    Side note: Injected, ingested and absorbed are different concepts. The basic idea of comparing the weight of Aluminum ingested versus injected seems a non-sequitur. I'll happily ingest a lot more beer than I will inject.

    I've come to the conclusion that the CHoP claim is technically true but is an intentional deception based on the pharmacokinetics of intramuscular versus oral aluminum. Aug 18, 2015 at 22:11

    Nobody ingests aluminum from vaccines.
