Lainie Ross presents a rigorous critical investigation of the development of policy governing the involvement of children in medical research. She examines the shift in focus from protection of medical research subjects, enshrined in post-World War II legislation, to the current era in which access is assuming greater precedence. Infamous studies such as Willowbrook (where mentally retarded children were infected with hepatitis) are evidence that before the policy shift protection was not always adequate, even for the most vulnerable groups. Additional safeguards for children were first implemented in many countries in the 1970s and 1980s; more recent policies and guidelines are trying to promote greater participation. Ross considers whether the safeguards work, whether they are fair, and how they apply in actual research practice. She goes on to offer specific recommendations to modify current policies and guidelines. Ross examines the regulatory structures (e.g. federal regulations and institutional review boards), the ad hoc policies )e.g. payment in pediatric research and the role of schools as reasearch venues), the actual practices of researchers (e.g. the race/ethnicity of enrolled research subjects or the decision to enroll newborns) as well aaas the decision-making process (both parental permission and the child's assent), in order to provide a broad critique. Some of her recommedations will break down current barrieres to the enrollment of children (e.g. permitting the payment of child research subjects; allowing healthy children to be exposed to research that entails more than minimal risk without requiring recourse to 407 panels); whereas other recommendations may create neew restrictions (e.g. the need for greater protection for research performed in schools; restrictions on what research should be done in the newborn nursery). The goal is to ensure that medical research is done in a way that promotes the health of curre
