Scatter Plot from Scientific Research

Spike RBD-specific IgG ELISAs were performed using sera collected at the indicated times against RBD proteins of SARS-CoV-2 WT, BA.5, XBB.1.5, JN.1, and KP.3 variants. Dashed lines indicate the limit of detection (IgG titer = 500). GMTs are labeled as black lines and shown above each column, with fold-changes and significance compared with the variant having the highest titer shown on the top.
