 HI titers against the homologous vaccine strain (A) post‐prime and (B) post‐boost; and HI titers (post‐boost) against heterologous vaccine strains after immunization with rH5 vaccines at (C) 0·1 μg of rH5 with emulsions or (D) 0·01 μg of rH5 with emulsions. Error bars represent standard deviation of the mean. All emulsion‐containing vaccines induced significantly higher HI titers compared with antigen alone at any dose for each pathogen strain with the exception of the HI titers against the A/Turkey/turkey with the lowest dose of rH5, where only the EM057 group induced higher responses than any dose of rH5 alone.
