Vaccine link to thyroid disease under investigation

NCT ID NCT07213141

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether COVID-19 vaccination might trigger Graves' disease, a condition where the immune system attacks the thyroid. Researchers will review medical records of 161 people who developed Graves' disease for the first time between March 2020 and October 2022. They want to see if cases that happened shortly after vaccination are different from typical cases, which could help doctors better diagnose and treat the disease.
