520 |a Autoimmune manifestations were reported in people infected with SARS-CoV-2. Repetitive exposure of mice to foreign antigen may lead to the onset of autoimmunity. We therefore investigated whether repetitive exposure to the SARS-CoV-2 spike protein could result in autoimmunity. To address this hypothesis, we repeatedly immunized C57Bl/6 mice with spike protein injected intraperitoneally. At the end of the immunization, mice which received spike protein produced anti-spike IgG but none of them developed anti-dsDNA antibodies or proteinuria. In conclusion, repetitive immunization with SARS-CoV-2 spike protein does not induce autoimmunity in the present mice model. Albeit reassuring, these results need to be confirmed by large epidemiological study evaluating the incidence of autoimmune diseases in individuals with repetitive SARS-CoV-2 antigen exposure
