Secondary objectives are to evaluate the humoral response in the nasal mucosa, and the capacity of antibodies to neutralize emerging variants of concerns and to prevent COVID-19.', 'detailedDescription': "The serious, even fatal, forms of COVID-19 preferentially affect elderly and fragile subjects. Among these populations at risk, people who are immunocompromised (either by a disease and / or its treatment) have a theoretical risk of responding less well to a preventive vaccination.\n\nThe main objective of this study aims to compare the vaccine response of immunocompromised people with healthy subjects (non-immunocompromised), i.e. to assess the serum humoral response (titre and neutralizing capacity of the antibodies induced) following vaccination with ComirnatyTM (i.e. BNT162b2, an anti-SARS-CoV-2 vaccine from Pfizer BioNTech) in immunocompromised persons in comparison to healthy subjects (non-immunocompromised).\n\nSecondary objectives are as follows:\n\n* To evaluate the antibody response in the nasal mucosa (titre and neutralizing capacity of the antibodies induced, collected by means of a nasopharyngeal swab) following vaccination with ComirnatyTM in immunocompromised people as compared to healthy subjects (vaccinated either with two doses of ComirnatyTM or, in a subgroup, with one dose of Astra Zeneca's VaxzeriaTM followed by one dose of ComirnatyTM).\n* Evaluate the serum and mucosal antibody response (titre and neutralizing capacity of the antibodies induced) against emerging strains of SARS-CoV-2 (so-called Alpha, Beta, Gamma, Delta strains).\n* Evaluate the post-vaccination clinical protection against the risk of COVID-19 infection (incident cases after vaccination)."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion

CD20 (or patients not treated at the time of the vaccine but who will be immediately after)\n * Common variable immune deficiency or other causes of severe hypogammaglobulinemia requiring chronic treatment with polyvalent immunoglobulin\n * Malignant tumor under anti-PD1 or anti-PDL1\n * People living with HIV\n * Complicated type 2 diabetes (with micro and / or macroangiopathy)\n * Group of
