Impact of BCG vaccination and metabolic risk factors on the severity of SARS-Cov-2 infection: a cross-sectional study from a tertiary care centre in northern India

Abstract

Background and aims: We present a study on the earliest cohort of patients infected with the SARS-CoV-2 virus who were admitted to the All India Institute of Medical Sciences (AIIMS), New Delhi. The primary objective of the study was to find the difference in the rate of intensive care unit (ICU) admission with coronavirus disease 2019 (COVID-19) in patients based on BCG vaccination status. The secondary objective was to assess risk factors for ICU admission and clinical course of patients with COVID-19.
