Abstract: The present invention provides methods of inducing anti-glatiramer acetate specific antibodies in a human subject afflicted with multiple sclerosis, comprising administration to the human subject of three subcutaneous injections of a 40 mg/ml dose of glatiramer acetate per week for at least 12 months, such that the level of anti-GA specific antibodies in the blood or serum of the human subject i) increases for up to about 6 months after an initial 40 mg/ml dose of glatiramer acetate of the administration is administered to the human subject; ii) increases at a greater rate during the first month after the initial 40 mg/ml dose of glatiramer acetate compared to the rate of increase after the first month to the third month after the initial 40 mg/ml dose of glatiramer acetate; iii) peaks at about 3 or about 6 months or between about 3 and about 6 months after the initial 40 mg/ml dose of glatiramer acetate; and iv) is higher than baseline at least about 12 months after the initial 40 mg/ml dose of glatiramer ac
