Aim: The aim of this study is to find out whether Subacute Thyroiditis may occur after Covid -19 Vaccination.

Materials and methods: This investigation was designed and held in “Kanaker-Zeytun” Medical Center and “Muratsan” University Hospital. 25 women (age: 35±7) with proved diagnoses of Subacute Thyroiditis were included in the study. The detailed history of disease was collected in order to understand how many of them survived Covid-19, whether they have been vaccinated and which vaccine had been done.

Results: It has been found that 18 from 25 patients had been vaccinated via vaccines of Chinese production. 7 participants had not been vaccinated at all. 7 from 18 patients furtherly had symptoms of Covid-19 and also developed Subacute Thyroiditis. Although 11 patients (61%) had not any complain after vaccination, during 4-6 weeks clinically Subacute Thyroiditis had appeared.

Conclusion: 61% of vaccinated patients with Subacute Thyroiditis developed Covid-19 without any significant clinical symptom. 28% of vaccinated patients had Covid-19 with huge manifestation of different symptoms. Vaccinated patients who developed painful swallowing, hoarseness, tenderness when gentle pressure is applied to the thyroid gland, elevated temperature, fatigue, feeling weak must be observed in order to exclude Subacute Thyroiditis after Covid-19.
