Background: Thyroid eye disease (TED), or Graves’ orbitopathy, is the most common extra-thyroidal manifestation of Graves’ disease, but it has only rarely been reported after SARS-CoV-2 vaccination. Autoimmune thyroid disease, including subacute thyroiditis and Graves’ disease, has been described following COVID-19 vaccination; we present a case series of TED occurring shortly after different COVID-19 vaccines to provide clinical data on this potential safety signal. Case presentation: We describe five women (mean age 47 years; range 27–69) who developed TED 3–20 days after COVID-19 vaccination with mRNA or adenoviral vector vaccines, three of whom had pre-existing thyroid disease. Presentations included ocular and retro-orbital pain, exophthalmos, headache, goiter, tremor, depressive symptoms, and, in one case, anterior neck pain and fever. TED severity (ETA/EUGOGO) ranged from mild to severe, with frequent findings of suppressed TSH, elevated thyroid autoantibodies, and inflammatory markers, as well as imaging evidence of exophthalmos, extraocular muscle enlargement, and diffuse or multinodular goiter. Management with intravenous corticosteroids, selenium, levothyroxine adjustment, and/or intramuscular corticosteroids led to improvement in thyroid function and inflammation by 3 months, although mild TED often persisted. Conclusions: This case series supports a temporal association between COVID-19 vaccination and new-onset or exacerbated TED in individuals with autoimmune thyroid disease. Although vaccination benefits outweigh potential risks, clinicians should remain alert to ocular and thyroid symptoms after immunization to ensure timely diagnosis and management.
