I'm not aware of any recent studies indicating that aluminum is a health hazard. It's still one of the active ingredients in antiperspirants and if there was any evidence to show that it was a link between it and Alzheimer's, you'd be hearing about it.
I'm not sold on the idea that aluminum is entirely safe, but if so, it certainly hasn't been proven. Pertaining as to any vindication of the Society, even if it was right, it would be no more or less significant than if it had been published in the Christian Science Monitor. Ultimately it's the instinct of the editor, the research of its reporters and the confirmation of data and scientific results that result in the accuracy of its publication. Finally, it's the freedom to publish (governmental and corporate) that gives the publication its drive and interspection.
