Estimation of Dynamics of Humoral and Cellular Immunity in COVID-19 Patients

December 9, 2021 updated by: Institute of Biophysics and Cell Engineering of National Academy of Sciences of Belarus
The goal of the project: to study the dynamics of the humoral and cellular immunity in patients after pneumonia caused by the SARS-CoV-2 virus at different time intervals, in order to predict the duration of immune protection

Detailed Description

  • to form study groups of patients (at least 60 patients in total) who have recovered from pneumonia of varying severity caused by the SARS-CoV-2 virus (at least 30 patients in each of the groups of patients who have had pneumonia in moderate and severe forms);
  • to investigate the parameters of cellular immunity (the content of antigen-specific T-cells to the main viral antigens - proteins S, N, M) in patients of different groups included in the trials, in dynamics 3, 6, 9 and 12 months after the COVID-19-associated pneumonia;
  • to investigate the indicators of humoral immunity (the content of IgG to the main viral antigens - proteins S, N, M) in patients of different groups included in the trials, in dynamics 3, 6, 9 and 12 months after the COVID-19-associated pneumonia.
