COVID-19, Immunity, Respiratory Failure, Vaccination
Conditions
Brief summary
The study is aimed at the clinical and laboratory characteristics of patients with completed vaccination against SARS-CoV-2 admitted to the hospital in the standard ward and intensive care unit due to the severe course of COVID-19.
Detailed description
The high number of patients hospitalized for COVID-19 significantly affects the entire healthcare system, where 70-80% of the total number of patients are unvaccinated, however, approximately 20-30% of patients hospitalized for the disease COVID-19 have undergone vaccination. The investigators assume the existence of several phenotypes of infection even in vaccinated patients, which may differ both in the rate of antibody formation, the dynamics of indicators of persistent virus replication, and the intensity of a potentially self-destructive inflammatory reaction and activation of coagulation. Early identification of patients with completed vaccination who have a higher risk of a severe course of COVID or a demonstrable inadequate immune response will allow individualization of treatment. Finding out the risk characteristics of the patients is a question and the difference in the type of vaccine on the severity of the course of hospitalization and the clinical outcome of the patients can contribute to the optimization of the vaccination strategy of the population and to the early identification of risk groups of vaccinated persons from the point of view of the timely deployment of available post-exposure prophylaxis/treatment procedures.
