The untold story of Albert Sabin, who developed the oral polio vaccine and became a controversial public health advocate for children worldwide Jonas Salk may be the name most associated with the polio vaccine, but it was Albert Sabin’s oral vaccine that made the goal of global eradication of poliomyelitis a possibility. Epidemiologist Karen Torghele draws on exclusive interviews, archival research, and the scientist’s own lab notebooks to deliver the first definitive biography of Sabin (1906–1993). She reveals a man driven by compulsion, whom Yale virologist John R. Paul described as “a fierce joy” when he was making new discoveries. But though his work reshaped virology and vaccine development, he was burdened by ego and an abrasive personality that would haunt his legacy. Sabin’s journey spanned continents and conflicts, from being a World War II hero to facilitating Cold War diplomacy, culminating in a risky experiment to test his vaccine in the USSR near the peak of the McCarthy era. Torghele combines biography and science to establish Sabin’s place in medical history, illuminating the research, politics, and private issues behind one of the twentieth century’s most controversial personalities—and offering insight into what we can learn from Sabin’s experiences as we encounter vaccine-preventable diseases like measles, address vaccine safety questions, and deal with deadly new viruses.
