Mpox-specific enzyme-linked immunosorbent assay (ELISA) (A and B) and 50% neutralizing antibody (NAb) titers (NT50) (C). Peak immunity was defined as 3 weeks after final vaccination. Titers less than 30 are considered negative. Horizontal red bars reflect median values. Numbers above the antigen data points reflect median titers.
