Association Between Covid -19 Vaccination And Severity Among The Covid 19 Patients In Urban Bangladesh

Abstract

The novel coronavirus that causes COVID-19 can be transmitted through human-to-human contact or indirectly with contaminated objects. On March 7, 2020, Bangladesh reported the first COVID-19 case. This study aimed to determine the prevalence of vaccination and its association with COVID -19 severity among the COVID 19 patients in urban Bangladesh. The study used the cross-sectional survey by collecting data randomly selected COVID-19 four dedicated hospitals (Both Government and Non-Government) of Dhaka city using a multistage stratified sampling method. In regression analysis we found significant association between vaccination and COVID-19 severity level p value < 0.01 and recovery time (p=0.019) but no significant association between vaccination and age (p=0.296). In the result of ROC curve, we found severity, recovery time and occupation significantly associated with COVID-19 vaccination. The study revealed that approximately 25% of the patients in the trial had a moderate COVID-19 infection. Also, the majority of patients who received vaccinations recovered in less than 14 days.
