Fig. 3

Groups of five mice were vaccinated i.m. with 1 or 10 µg A/Astrakhan/3212/2020 HA mRNA-LNP (H5 mRNA-LNP) or 10 µg Ovalbumin mRNA-LNP (control). Serum samples were collected 28 days after vaccination and serum antibody binding to HA proteins from diverse of H5 viral strains was determined using a bead-based multiplex binding assay. We measured antibody binding to the HA of (A) A/Astrakhan/3212/2020, (B) A/red fox/England/AVP-M1-21-01/2020, (C) A/pheasant/NY/22-009066-001/2022, (D) A/Vietnam/1203/2004, (E) A/Hubei/1/2010, and (F) A/Indonesia/5/2005. Binding is reported as mean fluorescence intensity (MFI) values. All data are shown as geometric means ± 95% confidence intervals. Data were compared using two-way ANOVA with Tukey’s multiple comparisons test. Values were log-transformed before statistical analysis. Data are representative of 2 independent experiments. A 1 µg vs. 10 µg *P = 0.004; (B) 1 µg vs. 10 µg *P = 0.0065; (E) 1 µg vs. 10 µg *P = 0.0002; all other comparisons *P < 0.0001. Source data are provided as a Source Data file.
