PURPOSE OF REVIEW: The wide spectrum of COVID-19 clinical manifestations demonstrates the determinant role played by the individual immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the course of the disease. Thanks to the large number of published data, we are beginning to understand the logic of the human response to a virus adapted to bat immunity. RECENT FINDINGS: Impairment of types I and III interferon responses may facilitate the occurrence of severe COVID-19 with reduced antiviral activity associated to potent inflammation. The human T and B-cell germline repertoire contain the specificities able to react against SARS-CoV-2 antigens. Although inflammation disrupts the structure of germinal centers, memory T and B cells can be found in the blood of patients after mild and severe COVID 19. SUMMARY: Further studies are indispensable to better understand the human immune response to SARS-CoV-2. The diversity of the individual reaction may contribute to explain the clinical manifestation spectrum. Immunological memory can be demonstrated in patients, convalescent from mild, moderate, or severe COVID-19, but we do not know whether asymptomatic individuals have memory of the virus. Tailored vaccination protocols may be needed for individuals with previous SAS-CoV-2 infection.
