> The mercury isn't primarily in there as a preservative.

This is wrong. Mercury was only ever present (intentionally, at least) in vaccines as part of thiomersol (a preservative).

> The vaccines have mercury or aluminum or other irritants for the designed purpose of provoking a strong immune response.

Aluminum is used as an adjuvant. Mercury containing compounds are not.

If you can cite a credible source to the contrary, I'd be much obliged.
