Testing the vaccine in ferrets before moving on to humans will take six to eight weeks, eliminating any head start over the traditional egg method.
Last month, UnitedHealth Group bought Humedica, which aggregates information on large patient populations for comparison purposes, and ferrets out at-risk patients.
Ferrets are often used in flu research because the animal's respiratory tract responds to flu viruses in much the same way as a human's.
Each team engineered the virus so that it could be transmitted through the air from ferret to ferret (ferrets, surprisingly, are good proxies for humans).
Ms. SANDY MONTEROSE (ASPCA): We've seen snakes, tons of birds, ferrets, rabbits, a couple pigs, and there is another--a separate team that is working with horses.
Past experiments have shown it to make viruses -- including the H5N1 bird flu virus -- more likely to infect ferrets, which are commonly used in flu research.
