Abstract

By the mid-1960s, nonhuman primates had become key experimental organisms for vaccine development and testing, and was seen by many scientists as important for the future success of this field as well as other biomedical undertakings. A major hindrance to expanding the use of nonhuman primates was the dependency on wild-captured animals. In addition to unreliable access and poor animal health, procurement of wild primates involved the circulation of infectious diseases and thus also public health hazards. This paper traces how the World Health Organization (WHO) became involved in the issue of primate supply, and shows how by the late 1960s concerns for vaccine development and the conservation of wildlife began to converge. How did the WHO navigate public health and animal health? What characterized the response and with what implications for humans and animals? The paper explores how technical standards of care were central to managing the conflicting concerns of animal and human health, biological standardization, and conservation. While the WHO’s main aim was to prevent public health risks, I argue that imposing new standards of care implied establishing new hierarchies of humans and animals, and cultures of care.
