Autoimmunity, COVID-19, Post-COVID-19 Syndrome and COVID-19 Vaccination covers all aspects of what is perhaps the most dramatic health crisis in the history of modern medicine. Severe acute respiratory syndrome coronavirus 2 (SARS-Co V-2) raised major concerns about the association between the virus and various autoimmune manifestations. Over 15 distinct autoantibodies and above 10 different autoimmune diseases were found to develop in COVID-19 patients. Moreover, evidence about recovered COVID-19 patients demonstrates that persistent systemic symptoms, which are believed to have an autoimmune-related mechanism, do exist. As it is of great importance to recognize those autoimmune manifestations of COVID-19 and post-COVID-19 syndrome to properly cope with their outcomes in the ongoing pandemic and the long-term post-pandemic period, this book fulfills a vital need in the medical community. – Describe the short and long impact of COVID-19 on autoimmunity- Provides understanding to the acute and chronic impact of the SARS-Co V-2- Gives insights into the long-term effects of COVID-19 on recovered patients- Provides conclusions on the novel terms "chronic post-COVID-19 syndrome", "post-acute COVID-19 syndrome", and "long COVID-19"
