Induction of immune responses to NetB antigens following vaccination and challenge by oral and intra-air sac routes Antigen-specific serum IgY against G-NetB(10) (a, b) and unG-NetB (c, d) were measured by indirect ELISA between first and second vaccine dose (day 21), between the second vaccine dose and challenge (day 28) and at post-mortem examination (day 35). Data are represented as median values with 95% confidence intervals
