Abstract

Introduction: The importance of vaccines is increasing day by day because the COVID-19 pandemic has been going on for about two years and there is no effective antiviral treatment. The purpose of this study was to compare the impact of vaccination status on the mortality of patients monitored in the intensive care unit with the diagnosis of COVID-19. Methods: Three hundred and forty-four patients treated in intensive care due to COVID-19 in three hospitals in Gaziantep were included in the study.
