Today's flu vaccines are prepared in fertilized chicken eggs, a method developed more than 50 years ago. The eggshell is cracked, and the influenza virus is injected into the fluid surrounding the embryo. The egg is resealed, the embryo becomes infected, and the resulting virus is then harvested, purified and used to produce the vaccine. Even with robotic assistance, "working with eggs is tedious," says Samuel L. Katz of the Duke University School of Medicine, a member of the vaccine advisory committee for the U.S. Food and Drug Administration. "Opening a culture flask is a heck of a lot simpler."One of the goals of the NCTM is to revolutionize vaccine production by moving it out of eggs. This cutting edge idea is a niche in the vaccine industry where A&M can clearly leap ahead of the competition, which only includes the likes of Novartis, Baxter, and Merck.
