Weight dynamics and survival of mice after challenge with HPAI H5N1 virus A/Chicken/Kurgan/3/05. Groups of 20 mice were vaccinated with live vaccines (106 TCID50) or with inactivated whole virion vaccines (2 μg HA in single dose). On day 30 mice were challenged by H5N1 A/Chicken/Kurgan/3/05 virus (∼100 LD50). Abrupt drop of weight curves denotes the death of all mice. Insertion represents the survival curves of the same experiment.
