Fig. 4: Neutralization of VSV-gfp-SARS-CoV-2-S in milk (top) and plasma (bottom).
In milk and plasma, neutralization is compared pre-vaccination, 7–10 days post 2nd dose, and six months post vaccination using the half-proximal inhibitory concentration (IC50). IC50 statistical calculations are measured using Mann–Whitney unpaired, nonparametric tests. Figures are shown as geometric mean. Line graphs represent non-linear regression models of inhibition at pre-vaccination (dotted, black line), 7–10 days post 2nd dose (solid, blue line), and six months post vaccination (solid, orange line).
