Serum antibody immune responses in Syrian hamsters immunized with FluCoVac-19 experimental vaccine. Syrian hamsters were twice immunized with 5×106 EID50 of H7N9 LAIV or FluCoVac-19 at 3-week intervals; sterile PBS was used as a control. Sera were collected 3 weeks after the 2nd dose and assessed by ELISA against whole influenza virus antigen (A) or against recombinant RBD protein (B). Data were analyzed by one-way ANOVA with Tukey’s post-hoc multiple analyses test. *—p < 0.05; ***—p < 0.001; ****—p < 0.0001
