Percentages of piglets with a protective (≥1:40) and a positive (≥1:10) maternally-derived antibody titre for H1N1pdm in the two groups of sampled piglets. The first sampling event was performed at 30 days of age and subsequent sampling events were performed at ~10-day intervals. Error bars represent 95% confidence intervals.
