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
