What validation do you have for your belief?

"The zapping works by damaging the glycoproteins and glcolipid antigens on 'any cell' that floats past the area being electrified."

My personal experience doesn't give any weight to the belief that blood electrification lowers immunity. I should know since I've done it almost every day since 1996. Sometimes I stop for a few days and there is no sickness at all that jumps me due to low immunity.
If the supposed antigen damaging was what causes the "die-off" effect then it would continue throughout all the weeks of treatment, but it doesn't. Die-off is normally only experienced at the beginning although it is sometimes experienced for the full 2 months of treatment with a severe long-lasting viral infection.

Dr Steven Kaali, patent owner for 2 blood electrification devices, said that electricity itself has no toxic side effects.

After my initial 2 months of blood electrification (4hz square wave) I had my blood analyzed by microscope and Dr. Tait said my blood looked almost perfect. Also, in the Biophysics Journal, Vol 58 Oct 1990, pages 897-903 the authors wrote that "Human erythrocytes [red blood cells] treated with AC for hours were shown to have normal shape, volume, and permeabilities to potassium and sodium." The research paper "On-Line Electrical Impedance Measurement for Monitoring Blood Viscosity during On-Pump Heart Surgery" said that the electric current goes around the blood cells, not through them, because the cell walls do not conduct electricity at frequencies less than 100KHz. That means the current flows through the blood serum (the liquid surrounding the blood cells) where the microbes are so they can be affected.
