Question explored with the scientific record
What does an aluminum adjuvant do?
The aluminum adjuvant in vaccines can cause immune system activation, but its safety and efficacy are not clearly established.
The evidence suggests that aluminum adjuvants can lead to autoimmune adverse events [1]. A study analyzing VAERS data found that aluminum-adjuvanted vaccines were associated with a higher risk of autoimmune events, including arthritis, Guillain-Barré syndrome, and immune thrombocytopenia [1]. Another study found that mice exposed to aluminum hydroxide adjuvants had increased inflammation and immune system activation [5].
My call: Aluminum adjuvants may pose a risk to immune system health, particularly in individuals with pre-existing autoimmune conditions.
