Fig. 6From: Immunogenicity and effectiveness of a bivalent influenza A/H1N2 vaccine strain against seasonal human influenza A viruses in miceImmunogenicity of inactivated candidate vaccine strains as measured by plaque reduction neutralization assay (PRNT) for the collected sera from vaccinated and control mice groups (n = 16 per group) at different time points post-vaccination. The sera plaque neutralization assay was done against influenza A/H1N1 (a) and A/H3N2 (b). Statistical analysis was performed using one-way ANOVA followed by Tukey’s post hoc test. The significant differences are indicated (*P < 0.05 and non-significant = ns)Back to article page
