A
major new peer-reviewed scoping review by Dr. Claudia Chaufan et al. analyzed
109 published studies on COVID-19 vaccination and autoimmune disease — and the findings are worrisome.
Across dozens of countries and all major vaccine platforms, the same pattern emerged:
COVID-19 vaccination is repeatedly associated with autoimmune flares, relapses, and entirely new autoimmune diseases —
including multiple sclerosis, lupus, type 1 diabetes, rheumatoid arthritis, Graves’ disease, Hashimoto’s thyroiditis, and more.
More than half the studies suggested a causal link.

Study Types
The authors examined 109 published studies spanning every major research design used in autoimmune safety literature. This diversity strengthens the signal: the same autoimmune patterns appear regardless of methodology, country, or vaccine platform.
- 52 case reports (47.7%)
- 15 case series (13.7%)
- 28 cohort studies (25.7%)
- 12 cross-sectional studies (11.1%)
- 2 randomized controlled trials (1.8%)
Condition-by-Condition Breakdown
1. Multiple Sclerosis (MS)
36 out of 109 studies (33.1%)
Included flares, relapses, worsening symptoms, and new-onset MS.
2. Systemic Lupus Erythematosus (SLE)
31 out of 109 studies (28.4%)
Included cutaneous lupus flares, multi-organ lupus onset, severe pediatric SLE, lupus myocarditis, etc.
3. Type 1 Diabetes Mellitus (T1DM)
16 out of 109 studies (14.7%)
Included abrupt-onset autoimmune diabetes, DKA, beta-cell failure, hyperglycemia, and worsening glycemic control.
4. Graves’ Disease
13 out of 109 studies (11.9%)
Included both flares and new-onset hyperthyroidism, often within days to weeks post-vaccination.
5. Rheumatoid Arthritis (RA)
13 out of 109 studies (11.9%)
Included severe RA flares, joint swelling, EBV reactivation, and new-onset RA.
6. Hashimoto’s Thyroiditis
Included within the autoimmune thyroiditis pool.
No flares were documented — but new-onset Hashimoto’s cases were reported.
7. Studies Involving Multiple Autoimmune Conditions
11 out of 109 studies (10.1%)
Reported clusters or overlapping conditions (e.g., SLE + antiphospholipid syndrome, MS + autoimmune antibody emergence, thyroiditis + diabetes).
Causality Assessment
- Suggested causal link: 61/109 (56%)
- Unclear causal direction: 22/109 (20.2%)
- No causal direction proposed: 26/109 (23.9%)
Autoimmune Flares vs. New Disease
- Flares/relapses of existing autoimmune disease: 65/109 (59.6%)
- New autoimmune disease in autoimmune patients: 12/109 (11%)
- New autoimmune disease in previously healthy individuals: 27/109 (24.8%)
Taken together, these data form the most comprehensive map to date of autoimmune outcomes following COVID-19 vaccination. Across 109 studies spanning every major autoimmune category, researchers documented: recurrent autoimmune flares, new diagnoses in already autoimmune-vulnerable patients, and entirely new autoimmune diseases in previously healthy people.
The signal appears across continents, across vaccine platforms, and across every study design — including case reports, case series, observational cohorts, and controlled data.
This is a safety signal that can no longer be dismissed or minimized.
