Determine Toxicity and Antibody Responses With a KLH Conjugated Bivalent Vaccine Containing GD2 Lactone, GD3 Lactone With Immunological Adjuvant QS-DG or OPT-821 in Patients With Disease Free AJCC Stage III or IV Cutaneous Melanoma

6 vaccinations (on weeks 1, 2, 3, 8, 20 and 32) which will contain the same KLH conjugates with GD2L and GD3L. All vaccines contain KLH conjugates containing 30mcg of GD2L and 30mcg of GD3L and QS-DG or OPT-821. The initial 8 patients will receive the same QS-DG or OPT-821 vaccine dose in all of their vaccines. This dose will be 50 mcg for the first patient, 75 mcg for the second patient and 100 mcg for the third through eighth patients. In all subsequent patients the 1st, 4th and 5th vaccinations will include 150 mcg of OPT-821. The 2nd and 3rd vaccinations will contain 100 mcg of OPT-821 and the 6th vaccination will contain 200 mcg of OPT-821.
