The University of Tokyo and Shimane University have developed a vaccine that can be taken orally by eating rice. It works on mice, what doesn't these days, and could be developed into a vaccine that treats allergies in humans.
Gee, another reason to eat rice. Just what I need. Seriously though it's a great idea. But they have missed the target market widely. Only when they can incorporate the vaccine into burgers, chips and fast food will it have any impact in America, Europe and Australia. But then again the researchers were Japanese and what did they have an abundance of to work with? I thought Westerners suffered more from allergies than any other race due to we being to clean and the body not being able to handle germs as it was designed.
