The Cutter Incident: How America's First Polio Vaccine Led to the Growing Vaccine Crisis

After a wave of books celebrating the 50th anniversary of Jonas Salk's polio vaccine, Offit's troubling account is the first to focus on a largely forgotten aspect—one with negative repercussions 50 years later. In a nuanced examination of a complex story, Offit, a professor of pediatrics and expert in infectious diseases, relates how Cutter Laboratories, one of several pharmaceutical companies licensed to produce Salk's killed-virus vaccine, shipped many lots of vaccine containing live virus, creating a mini polio epidemic: 40,000 children became ill, 200 were permanently paralyzed, 10 died. Offit carefully examines how Cutter was and was not responsible: tests for detecting live virus at the time were simply not sensitive enough, but Cutter departed from Salk's safe production protocols. And while the company knew there was a problem, it failed to notify the government's oversight agency. Cutter faced costly lawsuits that have resulted, according to Offit, in today's vaccine crisis: shortages (think of last year's flu vaccine) due to pharmaceutical companies' unwillingness to risk testing and producing vaccines and face possible litigation. In another example of the law of unintended consequences, Offit shows how "the Cutter Incident" led Salk's vaccine to be replaced by a less safe one: Sabin's live-virus vaccine. (Oct.)
