Starting from a brief historical survey of earlier vaccine trials, it examines the moral processes involved in the polio vaccine trials, in the USA, first in the 1930s and then in the 1950s. It argues plausibly that the trials of the 1930s had informal, non-institutionalised moral frameworks driven by the logic of lesser harm. The morality of “lesser harm” means, for Halpern, the argument that no clinical intervention that is riskier than the disease itself should be attempted even experimentallyengWith permission of the license/copyright holdercommunityhealth ethicsBioethicsMedical ethicsHealth ethicsArticle
