Do vaccines ramp up the immune system, sometimes to the significant detriment of patients? Yes.

You have just had a heart transplant. You do not want to reject your new heart. Why, then, get a flu vaccine? Why get a swine flu vaccine with ASO3 adjuvant? Because your ignorant doctor advised you strongly to do so, after all the hype.
And what happened? You were 26 times more likely to have a severe, acute cellular rejection episode.
