Testing of convalescent-phase serum transfer as potential protection against influenza A(H7N9) virus infection. Mice received 40 μL of patient serum intravenously 12 hours before H7N9 virus infection. A) IgG titers from mouse serum samples collected 1 h before infection. B–D) Relationships between IgG, HI, and MN titers in human serum and IgG titer in mouse recipients of transferred serum. E) Virus titers in homogenized mouse lungs at day 3 after infection (mean ± SE). F) Relationship between Ig
