CYCS and COVID-19: As the Raman signals of the reduced form are significantlyhigherthan those of the oxidized form of cytochrome c,5 one can state that the Raman intensity of theband at 1584 cm–1 in Figure 2A,B represents an oxidized form of cytochrome(cyt c Fe3+) both for the control andthe cells upon incubation with the COVID-19 mRNA vaccine.
