A single-center COVID-19 vaccine experience with CoronaVac and BNT162b2 in familial Mediterranean fever patients.

A considerable number of FMF patients suffered from vaccine-related adverse events/attacks, particularly with BNT162b2. No serious events or mortalities due to vaccination were detected. Demographics, clinical characteristics and prior history of vaccination did not significantly affect these results. We observed an increased rate of adverse events/attacks with booster dose administration.
