FIG 2.

NT₅₀ analysis against Delta-spike SARS-CoV-2. The same sera from Fig. 1 were measured for NT₅₀ values against mNeonGreen Delta-spike SARS-CoV-2. Delta-spike SARS-CoV-2 contains the complete spike gene from the Delta variant in the backbone of mNeonGreen USA-WA1/2020 SARS-CoV-2. The NT₅₀ values are summarized in Table S1. The NT₅₀ values were measured and presented as described in Fig. 1. (A) Plot of NT₅₀ values against Delta-spike SARS-CoV-2. (B) Pie presentation of different NT₅₀ ranges. (C) Plot of NT₅₀ against Delta-spike SARS-CoV-2 of different age groups. (D) Plot of NT₅₀ against Delta-spike SARS-CoV-2 versus days post vaccination. In C and D, the numbers above indicate geometric mean titers. The whiskers indicate 95% confidence intervals. Statistical analysis was performed with the one-way ANOVA with Tukey’s correction for multiple-comparison test.
