Book by Hannah Wunsch
During the 1950s, the fight against polio brought together several major shifts in medical care, all detailed by Dr. Hannah Wunsch in her history of the 1952 Copenhagen epidemic.
Before this period, anesthesiology was often treated as a secondary trade rather than a dedicated specialty. For conditions like severe polio, tetanus, poisoning, or major surgical recovery, the primary challenge was keeping a paralyzed body alive when it could not breathe on its own. Anesthesiologists possessed the specific skills needed to manage airways, leading to the birth of the modern Intensive Care Unit.
This era also reshaped mechanical ventilation. While iron lungs had been used since the late 1920s, the 1952 epidemic exposed their limits when hospital wards ran out of machines. Doctors in Copenhagen shifted to positive-pressure ventilation—delivering air directly into the lungs through a tracheostomy tube—which proved vastly more effective and permanently changed respiratory medicine.
Progress was not always linear. In the 1930s, poorly designed vaccine trials caused paralysis in participants, setting back human trials for nearly two decades. Decades later, during the 1955 rollout of Jonas Salk’s vaccine, manufacturing flaws at Cutter Laboratories led to batches containing live virus. This incident damaged public trust and contributed to early vaccine skepticism. It also prompted health authorities to establish much stricter federal oversight and manufacturing regulations.
