Los estudios in vitro e in vivo muestran que el SARS-CoV-2 induce una respuesta inmune antiviral reducida; lo que puede ser una de las causas para que la infección provoque daño más severo en pacientes inmunocomprometidos y ancianos. Asimismo, se sugiere que la vacuna BCG podría ser una alternativa para estimular la respuesta antiviral reprimida en pacientes infectados con SARS-CoV-2.
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.
