Clinical Trial Summary

The aim of the SARS-CoV-2-CZ-PREVAL-II Study is to quantify the prevalence of participants with antibodies against SARS-CoV-2 and/or cell immunity against SARS-CoV-2 in specific subjects cohorts.


Description:

The aim of the SARS-CoV-2-CZ-PREVAL-II Study is to quantify the prevalence of participants with antibodies against SARS-CoV-2 and/or cell immunity against SARS-CoV-2 in four specific cohorts: participants with chronic illness, healthy volunteers participating in the Study of the Czech Academy of Science, healthcare workers, and healthy volunteers that participated in the "Herd Immunity Study SARS-CoV-2-CZ-Preval" in May 2020. The primary aim of the study is to estimate the number of people with anti-SARS-CoV-2-antibodies, i.e., people with COVID-19 history, or with vaccination against COVID-19. Antibodies test will focus on two main proteins of virus SARS-CoV-2: S-protein and N-protein. The secondary aims of the study are: - quantitative analysis of cellular immunity and the other relevant markers, - estimation of the proportion of participants with asymptomatic COVID-19 infection - quantification of anti-SARS-CoV-2 antibodies and cell immunity according to individual risk factors.

Intervention

Diagnostic Test:
Quantitative analysis of SARS-CoV-2 antibodies
The study will evaluate the current presence of infection, specific antibodies at least in the IgG class in blood plasma or serum (antibody tests focusing on two SARS-CoV-2 proteins: S-protein and N-protein).
Cellular immunity
Quantification of the level of cellular immunity from venous blood collected in approximately 30% of examined individuals.
