Levels of Ca/04-specific antibody in the lung lavage of pigs previously vaccinated with live-attenuated influenza virus (LAIV), whole-inactivated virus (WIV), or mock-vaccinated (NV) 5 days after pH1N1 challenge (Ca/04). Lung lavage was collected on day 5 following challenge and assayed for A) IgG and B) IgA levels specific to Ca/04 virus and C) Ca/04 neutralization titer. Neutralization titers were log2 converted and reported as the geometric mean ± SEM. Antibody isotype data is expressed as the mean ± SEM optical density (OD) for 10 pigs per treatment group. A one-way analysis of variance with a Tukey’s post-test was used for statistical analysis and p-values <0.05 are indicated with connecting bars.
