In the developing world, infections in the respiratory and intestinal tracts are major causes of sickness and death, especially among children. Vaccine delivery systems that can target respiratory or intestinal mucosal tissue and stimulate immune response there have the potential to be particularly effective against these infections. Dr. Lo's project addresses two needs: the development of vaccine delivery systems that do not require needles and the design of systems that target specific tissues in the body. Using influenza vaccination as a model, Dr. Lo and his team are working to bind vaccine to specially designed molecules that target mucosal tissue.
