Impact of prior vaccination on clinical outcomes of patients with COVID-19.

ABSTRACT: Fully vaccinated people remain at risk of Coronavirus Disease 2019 (COVID-19). We examined association between prior vaccination and clinical outcomes in patients with COVID-19. Overall, 387 patients with mild-to-severe COVID-19 were enrolled.
