Introduction: Corona virus is a family single stranded RNA virus. Covid 19 the disease spectrum varies from asymptomatic infections to severe disease requiring mechanical ventilation. Chest X-ray and computed tomography are primary imaging tests for diagnosis, follow up and complications in this pandemic era. This study was intended to correlate the clinical severity, radiological features, and vaccination status with the outcome of hospitalized COVID 19 patients. Materials And Methods: This retrospective study included 757 admitted covid-19 patients in a dedicated tertiary care hospital. The patient’s data concerning medical history, vaccination history, laboratory findings, radiological features, severity and outcome were extracted from medical records for subsequent evaluation, interpretation and correlation. Results: A total of 757 patients included in the study, the mean agewas52 years with male preponderance. Majority of them had mild disease (52.8%), moderate and severe disease were (31%) and (13.5%) respectively. In this study 74.5% of people were vaccinated and 25.5% unvaccinated. To assess the severity of the disease chest X-rays were done. In that 32.5% were normal, 66.05% had consolidation. Bilateral involvement was seen in 45.18%.it was observed that involvement of left lung was more than the right. Upper zone involvement was associated with severe disease (67.6%).When compared with vaccination status patients, unvaccinated had more severe disease correlating with chest X-ray features in severity. Conclusion: This present study emphasizes the importance of covid vaccination; patients who didn’t receive vaccination had more severe disease and was evidenced by involvement of the lung showing severity of radiological features in chest X-ray.
