Blood will be sampled before starting treatment and at 3, 6, 9, and 12 months after starting treatment from newly diagnosed untreated patients along with patients who stopped treatment for 3- 6 months (before study). Participants in the control group will have their blood only drawn once. Patients will also have clinical assessment (including Expanded Disability Scale Scores (EDSS)) at each visit and MRI scans as clinically indicated (at time 0 and 12 months).

Non-probability sampling

- Definite MS by McDonald criteria; Relapsing-remitting disease (RRMS) about to be started on interferon-β, secondary progressive disease (SPMS) about to be started on cyclophosphamide therapy, or RRMS on treatment but experiencing an acute exacerbation.
- Healthy adult subjects who are not known to have an autoimmune disease.
