Recent Mumps-Measles-Rubella Vaccination Probably Reduces COVID-19 Severity: A Proposed Strategy For Close-Contacts Of Patients

several of the proteins produced by the SARS-CoV-2 virus inhibit interferon (IFN) and IFN gene responses, thus abating the innate immune response during the initial infection. Several US and European investigators have reported in the past trained immunity after BCG or measles vaccination: an enhanced non-specific (innate) immune response to non-related pathogens, which for BCG can last a year. However, BCG might be too strong a stimulus which we preferred not to use in the light of the cytokine storm-like syndrome in some patients with advanced COVID-19.
