ATLANTA (AP) - This year's flu season has shaped up to be the worst in three years, partly because the vaccine didn't work well against the viruses that made most people sick, health officials said Thursday.

The 2007-2008 season started slowly, peaked in mid-February and seems to be declining, although cases are still being reported, according to the Centers for Disease Control and Prevention.

Based on adult deaths from flu and pneumonia, this season is the worst since 2003-2004 - another time when the vaccine did not include the exact flu strain responsible for most illnesses. the rest image
