Vaccine-derived poliomyelitis and postpolio syndrome: an Italian Cutter Incident.

Post-polio syndrome is a condition characterized by increased muscle weakness, atrophy, fatigue and pain developing several years after the acute polio event. We describe a 52-year-old patient who experienced post-polio syndrome; he had contracted acute paralytic poliomyelitis at 12 months of age, shortly after the third dose of Salk polio vaccine.
