Abstract

Introduction: In this study, chest CT scan findings were compared in vaccinated and unvaccinated patients with COVID-19 aged 50-20 years.
Methodology: Patients aged 20-50 with covid-19 were included in the study. The findings in the chest CT scans of the patients were recorded in checklists based on the radiologist's report. After collecting the data, with the help of SPSS software, the frequency of the data and the relationship between the data were investigated.
Findings: A total of 189 patients with an average age of 35.71 ± 6.56 years were included in the study, of which 109 patients (57.7%) were female and the rest were male. The most common finding in the CT scan of the patients was ground glass opacity, which was observed in 146 patients (77.2%). There was a significant difference in the frequency of consolidation, bronchial wall thickening, ground glass opacity, Halo Sign, and Reverse Halo Sign among the three groups (in all cases, p<0.001) so that their prevalence was the highest in unvaccinated patients and the lowest patients with Complete vaccination. There was a significant difference between the percentage of lung involvement in the 3 groups (p<0.001), so that the highest lung involvement was observed in the non-vaccinated group and the lowest in the fully vaccinated group.
Conclusion: Based on the results obtained in the present study, vaccination against covid-19 leads to a decrease in the severity of the radiological manifestations of this disease.
