Brief Summary:
Determination of both the degree and duration of the immunity provided after receiving the BNT162b2 vaccine against SARS-Cov-2.

Condition or disease Intervention/treatment
COVID-19 Healthy Volunteers Chronic Disease Hematological Malignancies Solid Tumor Biological: BNT162b2 Biological: Other vaccine against SARS-Cov-2

Detailed Description:
The purpose of this study is to assess the kinetics of antibodies against SARS-CoV-2 as well as the kinetics of the immune system's cell subpopulations and cytokines associated with the immune system in healthy volunteers receiving the BNT162b2 vaccine against SARS-Cov-2 of the Pfizer/BioNTech companies or any other vaccine authorized and administered by the Ministry of Health. Immunoassays will be performed at serum collection points before and after vaccination, as set out in this study.
