To prevent avian influenza in waterfowl through a simple, non-invasive and needle-free route, they immunised ducks orally with an inactivated avian influenza virus (H9N2; IAIV) combined with CpG DNA and high-dose glucose. They then investigated the local and systemic immune responses of the ducks. In addition, immune protection was assayed after viral challenge....
