CHICAGO (Reuters) - Even as U.S. officials this week awaited the arrival of a sample of the new bird flu virus from China - typically the first step in making a flu vaccine - government-backed researchers had already begun testing a "seed" strain of the virus made from the genetic code posted on the Internet.
This new, faster approach is the result of a collaboration among the U.S. government, vaccine maker Novartis and a unit of the J. Craig Venter Institute, which is using synthetic biology - in which scientists take the genetic code of the virus and use it as a recipe to build the virus from scratch.
