IFNB1 and myeloid sarcoma: Studies in MS patients demonstrated that interferon-beta, glatiramer acetate, teriflunomide, fumarates, and natalizumab did not impact vaccine efficacy, while cell-depleting agents (ocrelizumab, rituximab, ofatumumab, alemtuzumab, and cladribine) and sphingosine-1-phosphate modulators likely attenuated vaccine responses [24].
