were confirmed with RT PCR. Patients were randomly divided in to two groups. Group I (vaccinated) comprised of

45 patients and group II (non-vaccinated) comprised of 65 patients. Severity of disease, hospital stay and

mortality were compared between both groups. Data was analyzed by SPSS 24.0.

50.54±12.76 years. Mean BMI was 26.23±2.44 kg/m2. 10 (22.22%) patients in vaccinated group and 40 (61.54%)

in nonvaccinated group had severe covid-19 disease, a significant difference was observed regarding severity of

disease between both groups with p-value <0.05. Mortality rate and hospital stay were also high in nonvaccinated

patients as compared to vaccinated (p-value <0.05).
