Are trace amounts of formaldehyde, mercury, or aluminum in vaccines harmful?

Question

Accepted Answer

Trace amounts of formaldehyde, mercury, or aluminum in vaccines are not shown to be harmful at the levels used in approved vaccines.

The body naturally produces formaldehyde as part of normal physiological function, and formaldehyde is present in higher concentration within people than what appears in vaccines. There is also no scientific evidence that the low levels of mercury or aluminum used in approved vaccines can be harmful. These substances are toxic at high amounts, but approved vaccines use only trace quantities.
The body already contains formaldehyde at higher levels
Formaldehyde is produced by the human body as part of normal physiological function. The claim made here is that formaldehyde is present in higher concentration within people than in vaccines, placing the comparison in terms of what the body already contains.
Low mercury and aluminum levels in approved vaccines have no evidence of harm
The information provided states that there is no scientific evidence that the low levels of mercury or aluminum in vaccines can be harmful. It frames the safety discussion around the fact that the quantities used in approved vaccines are small.
Toxicity depends on dose, including for naturally occurring substances
The explanation relies on the pharmacological principle “the dose makes the poison,” meaning toxicity depends on the amount present. It gives the example that even water can be harmful in huge quantities, illustrating that natural substances can cause harm when the dose is large.
Approved vaccines use only trace amounts of these chemicals
The key point is that formaldehyde, mercury, and aluminum are described as toxic to the human body in high amounts, while only trace amounts are used in approved vaccines. In this framing, the difference between harm and safety is the quantity delivered by vaccination.
