Figure 3. SARS-CoV-2 <t>IgG</t> and neutralizing antibody responses (A and B) Serum IgG titers against wild-type SARS- CoV-2 RBD protein (A) and pseudovirus neutralizing antibody titers (ID50) against SARS-CoV-2 variants (B) for non-elderly (left side) and elderly (right side) participants (n = 10 per dose group, and n = 6 for the placebo group). Participants received one injection of VLPCOV-01 (0.3, 1.0, or 3.0 mg), 30 mg BNT162b2, or placebo on day 1 (week 0). Logarithmic values are reported as geometric mean titers for serum IgG and neutralizing antibody against pseudovirus. Bars indicate 95% CIs. (C) The correlation between serum neutralizing antibody titers against pseudovirus Wuhan (wild type) and IgG antibody titers against SARS-CoV-2 RBD protein following booster vaccination. Pearson’s product-moment correlation coefficient and p value were calculated following log trans- formation of source data (r = 0.950, p < 0.001).

(A-B) Maximum intensity projections of merged dsRNA ( A-B , red) staining with the N protein ( A , white) or Nsp6 ( B , white) in A549-EV and A549:N cells. Nuclei were Hoechst stained (blue). Note that DVG-B encoded GFP is depicted (green). Scale bar indicates 20μm. Insets depict magnified cell regions indicated by the white boxes of dsRNA and N protein co-staining ( A ) or dsRNA and Nsp6 co-staining ( B ). Scale bar indicates 5μm.

Figure 3. SARS-CoV-2 IgG and neutralizing antibody responses (A and B) Serum IgG titers against wild-type SARS- CoV-2 RBD protein (A) and pseudovirus neutralizing antibody titers (ID50) against SARS-CoV-2 variants (B) for non-elderly (left side) and elderly (right side) participants (n = 10 per dose group, and n = 6 for the placebo group). Participants received one injection of VLPCOV-01 (0.3, 1.0, or 3.0 mg), 30 mg BNT162b2, or placebo on day 1 (week 0). Logarithmic values are reported as geometric mean titers for serum IgG and neutralizing antibody against pseudovirus. Bars indicate 95% CIs. (C) The correlation between serum neutralizing antibody titers against pseudovirus Wuhan (wild type) and IgG antibody titers against SARS-CoV-2 RBD protein following booster vaccination. Pearson’s product-moment correlation coefficient and p value were calculated following log trans- formation of source data (r = 0.950, p < 0.001).
