Brief Summary

The question of the immune response of the population, particularly of professional populations in contact with vulnerable populations (such as those with chronic conditions such as cancer), is an important issue. Knowing the evolution of this response over time in this population can help answer outstanding questions. The PRO-SERO-COV study is a seroprevalence study of caregivers working in the hospital sector with a follow-up at 3 months and 12 months. The objective is to evaluate and monitor at 3 and 12 months the serological immune status to an infection by the SARS-CoV-2 virus in active volunteer professionals working at the Institut Bergonié with different types of exposure: healthcare professionals and professionals in other services.

Outcome Measures

Primary Outcomes (1)

  • Rate of Positive Serological Immune Status to a Previous Infection by the SARS-CoV-2 Virus at Inclusion

    Total antibodies (IgG and IgM) directed against the N (nucleocapsid) protein of the virus were determined by ECLIA on a Cobas® 8000 (Roche Diagnostic, France) with the Elecsys Anti-SARS-CoV-2 kit. Serum was also tested by ELISA with the SARS-CoV-2 (IgG) ELISA Kit (EuroIm-mun, France). These ELISA and ECLIA tests were carried out in the medical biology laboratory of the Institut Bergonié. Serological immune status to a previous infection by the SARS-CoV-2 virus was evaluated for each patient and defined as : * Positive in case of positive ELISA test AND/OR positive ECLIA test * Negative otherwise

    Time 0 (Inclusion)

Secondary Outcomes (6)

  • Rate of Positive Serological Immune Status to a Previous Infection by the SARS-CoV-2 Virus at 3 Months

    3 months

  • Rate of Positive Serological Immune Status to a Previous Infection by the SARS-CoV-2 Virus at 12 Months

    12 months

  • Number of Health Care Workers With Active COVID-19 Infection
