ABSTRACT

Background: The lack of an effective antiviral treatment in the COVID 19 pandemic is increasing the importance of vaccines day by day. Materials and Methods: The study was scheduled between October 1, 2021 and January 7, 2022. COVID-19 PCR negative cases, cases whose vaccine information could not be reached, and cases under 18 years of age were excluded from the study. The cases in the service and the ICU, the cases that died and did not die during the follow-up in the ICU, and the vaccinated and unvaccinated cases were compared among themselves by dividing them into two groups. Results: The mean age, presence of comorbid conditions, length of stay, time elapsed after the last dose of vaccine and some laboratory values were found to be higher in ICU cases than in cases hospitalized in the service. The mean age and intubation rate were higher in the patients who died in the ICU compared to the survivors. The intubation rate was higher and the length of stay in the ICU was longer in unvaccinated cases compared to vaccinated cases. Conclusion: In our study, it was determined that the COVID 19 vaccines reduced the hospitalization of the patients in the early age groups, the length of stay in the ICU, and the admission to intubation. The reason for the significant difference in terms of mortality was thought to be due to the excess of comorbid conditions and higher average age in vaccinated cases.
