Volunteers From the Institute Curie and Institute Pasteur Staff Who Are Not Showing Active SARS-CoV-2 Infection Clinical Trial
Official title:
COVID-19 Study of the Serological Response Against the SARS-CoV-2 Virus in 2 Types of Employees, Hospital and Non-hospital, at Institute Curie and Institute Pasteur
This research proposes to study a large healthy population active for the presence of antibodies directed against the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus and this over time. After verification of the inclusion criteria and information by the coordinating investigative doctor, the volunteers sign a written consent. A nurse will take blood samples under safe conditions compatible with the pandemic period and while respecting the protection of the volunteer's personal data. The blood samples will be taken at 4 times for Institute Curie and Institute Pasteur: T0 (day of inclusion), between 6 weeks and 3 months ,6 months and 12 months post-inclusion. Each blood sample consists of a collection of 5 mL of blood in a dry tube. The serum samples will be extracted and collected prospectively from the blood samples. The nasopharyngeal swabs will be performed at 3 times: , between 6 weeks and 3 months, 6 months and 12 months post-inclusion for Institute Curie staff who have had at least one of the following four criteria on the sample or questionnaire carried out at T0: - have had RT-PCR+ - and/or presence of antibodies at the 95% threshold - and/or anosmia/ageusia - and/or digestive syndrome with associated respiratory signs. In case of infection between sampling times, if the volunteer meets one of the four criteria above, a nasopharyngeal swab will be performed during the following visits. The nasopharyngeal swab shall also be proposed to volunteers not meeting the 4 above listed criteria in order to have a control group (about 100 volunteers) for future statistical analyses. If the volunteers accept, naso-pharyngeal swab shall be performed between 6 weeks and 3 months, 6 months and 12 months after inclusion. For volunteers already included at Institute Curie : in case of proved (RT-PCR+ or antigenic +) or very likely (anosmia and/or ageusia, and/or digestive syndrome with associated respiratory signs) between 2 sampling times already planned in the flow chart, blood samples and nasopharyngeal swabs shall be performed. Those shall be performed if time since last planned sampling(s) has been more than 3 weeks or if time until next sampling(s) is more than 3 weeks. The blood samplings and nasopharyngeal swabs will be performed at 4 times for Institute Pasteur personnel: at T0 (inclusion day), between 6 weeks and 3 months, at 6 months and 12 months post-inclusion
