Scientists could be a step closer to creating a universal flu vaccine.

FOX's Colleen Cappon reports in this edition of "Housecall for Health":

Continuously changing flu strains keep researchers playing catch-up every season, but a team at the Imperial College London says a specific type of T-cell, or immune-system fighter cell, called CD8, could be the answer to preventing all types of flu. In study participants, a higher presence of CD8 meant less severe flu symptoms. Health officials say producing more of these cells could lead to a universal flu vaccine.
