From: Recombinant influenza H9N2 virus with a substitution of H3 hemagglutinin transmembrane domain showed enhanced immunogenicity in mice and chicken

Figure 4

Mice immunized with H7N9-TM showed higher survival rate and less body weight loss. (A) Anti-HA serum IgG titers against H9N2-WT and H9N2-TM. (B) Survival rates of immunized mice challenged with heterologous H9N2-YYS01 strain. *Indicates p < 0.05; **indicates p < 0.01. n = 5. (C) Body weight loss of immunized mice challenged with heterologous H9N2-YYS01 strain. * indicates p < 0.05; **indicates p < 0.01. n = 5.
