AMES, IOWA — Iowa State University researchers are putting flu vaccines into the genetic makeup of corn, which may someday allow pigs and humans to get a flu vaccination simply by eating corn or corn products.

According to the researchers, the corn vaccine would also work in humans when they eat corn or even corn flakes, corn chips, tortillas or anything that contains corn, Mr. Harris said. The research is funded by a grant from Iowa State University's Plant Sciences Institute, and is their Biopharmaceuticals and Bioindustrials Research Initiative.
