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).

Where, n = number of individuals, IgA-Immunoglobulin A, IgM-Immunoglobulin M and IgG-Immunoglobulin G, control (n-14), infected (n-23, Symptomatic n-10 and Asymptomatic n-13) and contact (n-24).

Article Snippet: For IgA and IgM quantification, RBD (SARS-CoV-2 spike RBD recombinant protein, mFc-Tag, CST # 41701S) antigen at a concentration of 200ng/well was coated in a 96-well high binding micro titre plate (HIMEDIA-EP1) in 1x TBS pH-7.4 for 2h at 37□.
