First seen Nov 01, 2025 · Last updated May 23, 2026 · Updated 28 times

Summary

This study reviews medical records of 161 people who developed Graves' disease for the first time between March 2020 and October 2022. Researchers want to see if getting a COVID-19 vaccine may have triggered the condition and whether these cases differ from typical Graves' disease. The goal is to better understand any possible connection, not to prove the vaccine causes the disease.
