A physician who once lent his authority to the anti-vaccination cause narrates how political concessions and persuasive agitation helped precipitate a devastating smallpox outbreak. The account traces his public prominence and subsequent disgrace, the epidemic’s heavy toll on his community, personal bereavement, legal consequences, and growing remorse. Combining courtroom and political scenes with intimate confession, the narrative probes the clash between individual conscience and public health, the harms of misinformation and populist pressure, and the ethical burden borne by professionals whose public influence can determine the fate of vulnerable populations.
