Abstract
A paper in this issue discusses the use of multilayered polyelectrolyte films incorporating a hydrolytically degradable polymer for transcutaneous drug or vaccine delivery. Dried films could be deconstructed rapidly, and a model protein antigen (ovalbumin) and/or immunostimulatory molecules could be released with different kinetics. Both molecules could also be delivered to antigen-presenting cells in the skin (Langerhans cells). The described approach provides a new route for the storage of vaccines. Successful antigen processing and presentation to lymphocytes remain ongoing challenges before the concept can be used in the next generation of vaccines.
