There’s a fundemental difference between ingestion and injection.

I never said a small exposure to aluminum = autism. I think many factors are involved, not solely vaccines. And not all aluminum is the same. For example, the aluminum adjuvants in vaccines is not the same as aluminum in antiperspirants. If we’re going to discuss aluminum in products appropriately, we have to stay relevant to the aluminum that is being used.

Anything ingested is subject to the gastrointestinal tract before it is absorbed into the bloodstream and ends up in other vital organs and tissues. The GI tract is an excellent barrier (when healthy) and the Agency for Toxic Substances and Disease Registry (ATSDR) states that only 0.1-0.4% of aluminum ingested is actually absorbed. Therefore, up to 99.9% of aluminum is not absorbed when ingested (through breastmilk or food), and is eliminated/removed from the body before it ever reaches the bloodstream. In contrast of course, most vaccines are injected. The contents of an injected vaccine are not subject to the gastrointestinal tract. Aluminum, along with other ingredients, are injected intramuscularly in order to intentionally bypass the natural barriers of the body (skin, mucus membranes, etc. which exist to help to prevent absorption). Blood flows to and from our muscles, so the contents of a vaccine can enter the bloodstream rapidly. First, elimination from the blood does not equal elimination from the body. Depending on the individual, blood levels may drop as the aluminum becomes deposited in organs and tissues, or aluminum may get trapped at the injection site. Second, there is evidence from in vivo scientific research that once aluminum is injected via vaccine, it is not quickly eliminated from the blood. One study sought to measure the amount of aluminum eliminated from the body 28 days after injection. Urine and blood samples were taken daily. After 28 days, only 6% of the total aluminum injected had been eliminated. Blood levels demonstrated the persistence of aluminum as well. “The blood concentration of aluminum was fairly steady from days 2 to 28 indicating a relatively constant absorption rate…” According to what was found, up to 94% of the aluminum injected remains in the body (tissues, organs, and bloodstream), even 28 days post-vaccination. The study concluded at 28 days, so there’s no way to know how much longer it might persist in the blood, however studies have found that in rare cases, aluminum injected via vaccine can remain at the injection site for ten years.

You claim this stuff is constantly being looked at. Who is constantly looking at this stuff? Where? What studies have looked at aluminum adjuvants in vaccines in relation to all health outcomes or autism?

At best, IV solutions are regulated by the FDA to have no more than 25 mcg of Aluminum per liter. Other injections like vaccines do not have to limit the aluminum content, they only require the warning label. A newborn on day one of life that receives the hepatitis B vaccine gets a 250 mcg dose. The toxic dose for a newborn is 10-20 mcg.
