To test whether possible contamination with the neuritogenic P2 protein from peripheral nerve myelin contributed to the increased incidence of Guillain-Barré syndrome during the national influenza immunization program, monovalent and bivalent vaccines from each manufacturer were tested using a recently developed radioimmunoassay for P2 protein. No P2 protein was found in any of the vaccines tested.
