New methods of delivering vaccines.

From ScienceDaily researcher from the Northwestern University Feinberg School of Medicine has developed a new oral vaccine using probiotics, the healthy bacteria that are found in dairy products like yogurt and cheese. He has successfully used the approach in a preclinical study to create immunity to anthrax exposure. He also is using the method to develop a breast cancer vaccine and vaccines for various infectious diseases. This new generation vaccine has big benefits beyond eliminating the "Ouch!" factor. Delivering the vaccine to the gut -- rather than injecting it into a muscle -- harnesses the full power of the body's primary immune force, which is located in the small intestine.
