The Incidence of Graves’ Hyperthyroidism Before and After COVID-19 Messenger RNA Vaccination

Endocr PractPublished Retrospective cohort study

Authors' conclusion

There was no increase in new-onset GD after COVID-19 vaccination. Median free T4 was higher in patients with PVGD, but this was not statistically significant.
