MYTH 4: “Dr Sears says that the amount of aluminium in vaccines is more than injectable aluminium guidelines. He says that the FDA advises premature babies and any patient with impaired kidney function shouldn’t get more than 10 to 25 micrograms of injected aluminum at any one time, yet the total dose of aluminum can vary from 250 micrograms at birth (Hep B) to 295 - 1225 micrograms at 2, 4 and 6 months. He is a medical doctor, and he is worried that these aluminium levels far exceed what may be safe for young babies.”
There is a glaring error with Dr Sears aluminium information that would likely go over most people's heads. Vaccines are what's called a biological product. They have a different guideline to aluminium levels in food and a different guideline to aluminium levels in continuous nutritional intravenous products (parenteral nutrition).
Dietary aluminum is in such small quantities that it is not a significant source of concern in persons with normal elimination capacity. Premature babies do not have a normal elimination capacity, so the IV nutritional guideline needs to factor this in.
Dr Sears compares aluminium in intravenous nutrition products for preemie babies to aluminium in intramuscular vaccines. He is comparing the level of aluminium in vaccines to the wrong guideline.
Anti-vax sites are notorious for making this same error eg. they will compare environmental mercury from drinking water (a guideline determined by the EPA) to thimerosal in vaccines (a guideline determined by the FDA - for biological intramuscular injectables)
Here is the correct value:
Chapter 21 of the US Code of Federal Regulations [610.15(a)] limits the amount of aluminum in the recommended individual dose of biological products, including vaccines, to not more than 0.85-1.25 mg per dose.

MYTH 5: “But injected aluminium is different to ingesting it”.
Not really. With aluminium, absorption is extremely low from either route.
Ingestion via the gut IS different to
Injection IM - into muscle (vaccines) is different to
Injected IV - intravenously (directly into the bloodstream)
But you also have to consider how often you consume or inject these substances.
Water and food, which we ingest several times a day every day of our lives will *always* have a lower safety limit simply because we use them so often. It's really the aluminium from food and water that we need to watch. Even though very little retained, it can accumulate because we consume them daily, several times a day, over time. Vaccines are spaced out over months, so the aluminium contained within them do not have much of a chance to accumulate - the amounts are so small to begin with and the majority is excreted.
With the food and drinks you ingest, your gut mucosa filters out a lot of harmful substances and prevents them going into the bloodstream. So most aluminium that you eat, you would excrete before it even enters the bloodstream. That which does enter the bloodstream can also be excreted via the kidneys--> urine and bile. Less than 1% of the aluminium that you eat is absorbed by the body.

Even less is retained (in the tissues and skeleton)
Much of the injected aluminium from vaccines enters the bloodstream, but only a very, very small percentage of that will be "dissolved" in the blood - it's in the form of precipitate and is bound to carrier proteins (transferrin). Approximately 98 % of aluminium in the blood is excreted in the urine, and to a lesser extent bile. The unabsorbed aluminum is excreted in the feces. A diminishingly small amount may be retained.
We're talking about a minute fraction of two hundredths of bugger all.
Aluminium given intravenously (via continuous nutritional products for premmie babies - which is the guideline Dr Sears uses - ) has a much higher retention and accumulation value. Of course it does, because it goes straight into the bloodstream and the IV line is continuously there, feeding them all day long. And these tiny preemie babies have underdeveloped kidneys.
When determine the safety of aluminium in vaccines, ingestion of aluminium from food PLUS injection from vaccines is all factored into the formulation and regulation of vaccines when determining safe body burdens.
The amounts in vaccines fall within recommended guidelines when you compare it to the *correct* value.
