Healtcare workers undergoing SARS-CoV-2 vaccination (with RNA-vaccines) will be included on a voluntary basis. Blood samples will be collected before and after vaccination (1 -3 - 6 - 12 months). All the vaccination side effects will be registered.
Preliminary data support a possible molecular mimicry between SARS-CoV-2 and autologous components. This suggests the occurrence of autoimmunity during COVID-19. Consistently, autoimmunity may occur after SARS-CoV2 vaccination. The study aims to investigate the production of autoantibodies after vaccination in healtcare workers.
