NCT04844489

Brief Summary

Prospective, multicenter, non-comparative cohort study of immunocompromised people vaccinated against Covid-19 with the aim to know the humoral and cellular response to BNT162b2 vaccination against SARS-CoV-2 variants. This study will enroll patients in 5 parallel sub-cohorts of the same size, distinct according to the source of the immunosuppression: autoimmune or auto-inflammatory disease, HIV infection, multiple sclerosis, solid cancer, organ transplantation with prospective data collection and constitution of biological collections.

Outcome Measures

Primary Outcomes (1)

  • Proportion of patients with a neutralizing antibody titer greater than 1/10 towards the wild strain and the English VOC 202012/01, South African 501Y.V2 variants and any other variants that may emerge

    At the third injection visit and at one, six and twelve months after the last injection

Secondary Outcomes (9)

  • Proportion of patients with a positive serology by detection of IgG anti-receptor-binding domain (RBD) antibodies to the Spike protein of SARS-CoV-2 measured by the SARS-CoV technique -2 IgG II Quant assay (Abbott)

    At second and third injection visits and at one, six and twelve months after the last injection

  • Proportion of patients with a positive serology by detection of the anti-Spike protein IgG antibodies of SARS-CoV-2 measured by the Euroimmun technique

    At second and third injection visits and at one, six and twelve months after the last injection

  • Proportion of patients with positive anti-RBD IgG serology on D0

    At inclusion visit

  • Anti-RBD IgG level

    At second and third injection visits and at one, six and twelve months after the last injection

  • Antibody neutralization title

    At second and third injection visits and at one, six and twelve months after the last injection

  • +4 more secondary outcomes

Study Arms (1)

Blood samples

OTHER
Other: Blood samples for the study of the humoral response to SARS-CoV-2 variants and of the cellular response after vaccination against COVID-19

Interventions

Blood samples at: * D0 (the day of the injection of the SARS-CoV-2 vaccine), * during the 2nd injection as part of the national vaccination campaign (on D28) * during the 3rd injection for patients for whom a third injection is recommended (according to the recommendations in force) * then to M1, M6 and M12 of the last injection

Blood samples
