> aluminum is not safe
[Citation needed]
As I understand it, aluminum salts have been used for decades globally, administered to over 1 billion people in vaccines with no statistically significant indication that it is unsafe. For example, in a study[1] in Denmark including more than 1 million children, there were no statistically significant increases in risk for any autoimmune and developmental outcomes they studied.
If you're going to assert a lack of safety in something that has been used so much for so long, it would be helpful to cite methodologically sound studies and non-anecdotal data to back up that assertion.
