SARS-CoV-2 S protein-pseudotyped-vesicular stomatitis virus vector-based neutralization assay revealed that at this time point post infection the MVA-WT immunized animals also had detectable nAb against SARS-CoV-2 in serum (Figures 7A, B), which is in line with previous reports (67, 68). This evidence concerns the gene PROS1 and infection.
