Brief Summary
The main objective of the study is to describe the temporal curve of COVID-19 IgG and neutralizing antibodies over 24 months in an identified population of patients who presented with SARS-CoV-2 virus infection. The secondary objectives are to characterize the kinetics of the antibodies according to the severity of the clinical presentation and patient's characteristics and to determine if the anti-SARS-CoV-2 antibodies retain their neutralizing capacity over time. A sub-study aims to describe the kinetic of neutralizing antibodies (in blood and nasal mucosa) after vaccination.

Study Arms (1)
Group with biological samples
EXPERIMENTALCollection of biological samples (M0, M3, M6, M9, M12, M15, M18, M24) with associated data for the study of the kinetics of antibodies anti COVID-19 in subjects with documented SARS-CoV-2 infection (PCR and/or positive specific serology). In the vaccine sub-study: additional blood and nasopharyngeal samples before and after vaccination, up to 6 months.
Interventions
Biological samples : * Serum and plasma from each donor for the purpose of performing (if applicable) the SARS-CoV-2 serologic test * PBMC (peripheral blood mononuclear cells) * Nasopharyngeal samples (not mandatory) Associated data : * Demographic data * Description of clinical manifestations related to SARS-CoV-2 infection * Notion of hospitalization/ambulatory follow-up Blood Fractioning * Serum and plasma aliquoted and stored under 250, 500 and 1000 µL (at -80°C) * Separation of PBMC on Lymphoprep and freezing in liquid nitrogen for subsequent analysis of immune system cells
Eligibility Criteria
You may qualify if:
- Age \> 18
- Having had a confirmed infection with CoV-2-SARS by RT-PCR and/or serology (IgM and/or IgG specific as significant)
- Being vaccinated against anti-SARS-CoV-2 (vaccine sub-study)
- Benefiting from a Social Security system
- Having consented to participate in the study
- Accepting regular follow-up for 24 months
You may not qualify if:
- Protected person (under guardianship or trusteeship)
- Person under the protection of justice
- Person unable to express consent
