ABSTRACT

In vitro and in vivo studies show that SARS-CoV-2 induces a suppressed antiviral immune response, which may be one of the reasons the infection causes more severe damage in immunocompromised and elderly patients. Also, it is suggested that the BCG vaccine could be an alternative to stimulate the suppressed antiviral response in patients infected with SARS-CoV-2.
