I got rid of all my Amalgams and my low immunity continued. Now I believe that immunity is established in childhood and stays that way throughout your life. My low immunity allowed me to get the viral type of chronic fatigue syndrome and I bought the story-line from the health food stores that all ya gotta do is eat right and take hundreds of dollars worth of vitamins and your immunity will strengthen. NOT! I've also had candida and got rid of it using the Candida Zapper but I retreat for it once a month because of my immune weakness to it.
