A 'positive' test result only indicates the presence of normal human stress-protein
Reminder. A 'positive' test result only indicates the presence of normal human stress-proteins. There may be a lot of them, in order to reach the cutoff point and be declared 'positive', but that is not an immunity problem.
1984: Bob Gallo announces his creation of an HIV antibody test. Due to their short life span, the T-cells of the AIDS patients were not suitable for mass production of similar natured antigens, and an actual retrovirus could not be isolated, so immortal human leukemia cells were co-cultivated and co-stimulated with the cell culture. Gallo claimed that the allegedly isolated retrovirus had passed into the leukemia cells; the end result was that these normal human stress-proteins could be mass-produced and sold as test-kit antigens. This deceptive procedure was patented by Bob Gallo.(Gilles St-Pierre)
