COVID-19 Clinical Trial
Official title:
Study of the Neutralizing Power of Anti-SARS-CoV-2 (Anti-COVID-19) Serum Antibodies
Natural infection, vaccines and treatments (like monoclonal antibodies) lead to the appearance of a neutralizing power in the serum (due to induced or injected antibodies). This neutralizing power is recognized as a correlate of protection against a (new) infection. This study aims to measure the neutralizing power of the serum of patients (whether or not they have been infected with SARS-CoV-2) according to the treatments and/or vaccines received and to assess the durability of this power in the time.
Infection, vaccines and treatments (like monoclonal antibodies) lead to the appearance of a neutralizing power in the serum (due to induced or injected antibodies). This neutralizing power is recognized as a correlate of protection against (new) infection. The purpose of this study is to measure the neutralizing power of the serum of patients (whether or not they have been infected with SARS-CoV-2) depending on the treatments and/or vaccines received and to assess the durability of this power over time. The main objective is to measure and describe the evolution of the serum humoral response (titer and neutralizing capacity of anti-SARS-CoV-2 antibodies) following any intervention inducing or conferring neutralizing anti-SARS-CoV-2 antibodies (vaccines - whatever the mode of action -, monoclonal antibodies). The secondary objectives are: - to measure and describe the antibody response at the level of the nasal mucosa (titer and neutralizing capacity of anti-SARS-CoV-2 antibodies, collected by means of a nasal swab) following any intervention inducing or conferring neutralizing anti-SARS-CoV-2 antibodies SARS-CoV-2. - to describe the incidence of COVID in the study patients. ;
