Figure Lengend Snippet: A) Study schedule with median visit times. Ranges of visit times included in each visit are in parentheses. All times are in relation to the previous vaccine dose. Image generated with BioRender. B) Neutralizing titers against clade IIb MPXV as measured by microneutralization assay with 5% guinea pig serum. Mpox convalescent samples are from the indicated time point post-symptom onset. Naïve and experienced controls were collected pre-2022. Black bars represent the geometric mean. Samples with ID 50 values below the limit of detection (LOD) are assigned a value of 10, or ½ the LOD. C) Spearman correlation of IgG for the indicated protein versus MPXV neutralizing titers. Samples are from V4. D) Avidity index for IgG that correlated with MPXV neutralization in both naïve and experienced vaccinees in C. Only avidity measurements from samples with above background binding are included. Black bars represent the mean. Statistics for panel B were performed using the Kruskal-Wallis test with Dunn’s method for multiple comparisons and for panel D were performed using ordinary one-way ANOVA with Šídák’s multiple comparisons test. MPXV Conv, mpox convalescent patients; IMV, intracellular mature virion; EEV, extracellular enveloped virion.
Article Snippet: Briefly, ten different OPXV proteins were included in the panel: MPXV H3 (Sino Biological 40893-V08H1), MPXV A35 (Sino Biological 40886-V08H), MPXV A29 (Sino Biological 40891-V08E), MPXV A30 (Cell Sciences YVV15001A), MPXV M1 (Sino Biological 40904-V07H), MPXV B2 (Abbexa abx620100), MPXV A27 (Abbexa abx620105), MPXV B6 (Abbexa abx620118), VACV A33 (Sino Biological 40896-V07E), and VACV B5 (Sino Biological 40900-V08H).
