, I am so glad vumerity is working well for your daughter. Unless your daughter is experiencing significant side effects, I would presume that your daughter's physician would recommend sticking with her current treatment plan. As the old saying goes, "If it ain't broke, don't fix it." That said, your daughter has every right to pursue whatever treatment option she thinks would be best for her and her MS.
