Not a source but a plausible explanation. It's said to be a new breakthrough in adjuvants:

https://pubmed.ncbi.nlm.nih.gov/32531395/

https://pubmed.ncbi.nlm.nih.gov/26814441/

My concern with it is that it has phenomenal electromagnetic qualities for other purposes, miniaturized self-assembling circuits for example, but without proper testing it probably shouldn't be mass-deployed live within an environment that is saturated with an artificial electromagnetic field from phone towers, radio towers, military apparatuses, heavy machinery, huge sound systems, etc.

Aluminum-based adjuvants wouldn't have much reactivity to electromagnetic radiation but aluminum is cited as potentially causing some problems with memory, Alzheimer's if I remember correctly.

This study https://pubmed.ncbi.nlm.nih.gov/21157018/ appears to talk about the safety of ingesting aluminum through a normal dietary regimen (maybe relevant to the OP), but what if it is miniaturized down to something small enough to be used as an adjuvant? Could it then get into the brain?

Now, let me ask: does the following sound plausible?

Now imagine an advanced adversarial AI applied to any of these purely hypothetical combinations.

They told me to follow the science but I'm not sure that I'm doing it right. Is any of this fake news?
