Severity of SARS-CoV-2 infection among vaccinated individuals: A hospital-based study.

Introduction: Post-vaccination infections impart the need for real-world data on protection conferred by the vaccines against SARS-CoV-2. We aimed to evaluate the severity of post-vaccination COVID-19 and the predictors of severe disease.

Methods: This cross-sectional study analysed data from 307 patients admitted to the University Hospital KDU with confirmed COVID- 19 from March 1st to November 1st, 2021, after receiving at least a single dose of a vaccine against SARS-CoV-2.
