Researchers at Vanderbilt University Medical Center in Nashville are working on a universal flu vaccine that has the potential to protect everyone against all strains of the flu, anywhere in the world. Vanderbilt is the hub and coordinating center for this groundbreaking research being conducted around the world. Current flu vaccines can reduce the risk of some influenza by about 60 percent. This research would make it near 100 percent for all strains of influenza. Down through the years scientists have been puzzled at the different ways that the influenza strain can morph into something different while in the body. Such “morphing” as they call it leads to some of those vaccines being ineffective. That’s why researchers are studying the cells in those individual who become immune to the virus after vaccinations.
