    Deerfield, Illinois (ots/PRNewswire) - Baxter International Inc. (NYSE: BAX) announced today that it has voluntarily suspended enrollment in the Phase II/III clinical study currently underway in Europe of its PreFluCel influenza vaccine, due to a higher than expected rate of mild fever and associated symptoms in the clinical trial participants.
