Prefusion-stabilized RSV B18537 DS-Cav1 F elicits high neutralization titers against both subtypes A and B viruses. (A) Mice were immunized with either DS-Cav1 or postfusion B18537 F glyco-protein at weeks 0 and 3. Serum samples were taken at week 5. (B) Mouse sera were assayed for neutralization against subtype A and B strains. Each dot represents the serum titer from a single mouse. Average titer of each group is marked with a line and also labeled on the horizontal axis. (C) Sera from mice immunized with RSV B18537 F prefusion DS-Cav1 or postfusion immunogen were assessed for binding to the immobilized RSV B18537 F DS-Cav1, postfusion, DS-Cav1 bound by MPE8, or DS-Cav1 bound by D25. Average response of each group is marked with a red line. Statistical analyses in (B) and (C) were calculated by Mann-Whitney 2-tailed t test, ****: P < 0.001.
