Systemic toxicity will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Dose-limiting toxicity is defined as any of the following that are attributable to vaccine therapy: Any grade 3, 4 or 5 toxicity, Any grade \>=2 clinical autoimmunity with the potential to threaten critical organs (including lungs, heart, kidney, bowel, bone marrow, liver or central nervous system (CNS), or eyes), and any removal of a patient from therapy due to toxicity
