Comparison of protein expression induced by CVnCoV and CV2CoV mRNA. Expression of SARS-CoV-2 spike (S) protein in HeLa cells transfected with CVnCoV or CV2CoV mRNA, as indicated, detected using flow cytometric analysis via an S-specific antibody either with or without membrane permeabilisation, allowing detection of intracellular and cell surface expression, respectively. The geometric mean fluorescence intensity (GMFI) is expressed as mean + standard deviation (SD) of duplicate samples from two independent experiments. *** = p < 0.001 (t-test). WFI: water for injection.
