The smallest amount (in % of the initial suspension of bacteria or culture medium) that protects 50% of MDCK cells after infection with influenza viruses. Red color indicates the A/Lipetsk/1V/2018 (H1N1 pdm09) virus infection; blue color indicates the A/common gull/Saratov/1676/2018 (H5N6) virus infection. The results are from three independent experiments. .
