MMR-Impfstoff
MDSCs can also play a positive regulatory role. It is stated that MMR vaccine stimulates MDSC populations in people taking the vaccine, inhibiting septic inflammation and mortality that is broadly applicable not only to measles, mumps, and rubella, but extends to covid-19 induced cytokine inflammation. This vaccination inducement appears to be neither permanent nor chronic. Despite MDSC's being immunosuppressive in certain instances, the MMR vaccine itself is immunostimulatory.
