Final answer:
The Willowbrook State School case involved a series of studies conducted on mentally disabled children, infecting them with the hepatitis virus. The school defended this by claiming that the conditions of the school would likely lead to hepatitis anyway. However, many parents were not adequately informed about the risks involved.
Step-by-step explanation:
The subject of this question is the Willowbrook State School case in New York state, which involved a series of studies conducted from 1963-66 on children with mental disabilities. The school infected these children with the hepatitis virus, claiming that their unsanitary conditions would likely lead to hepatitis anyway.
Parents gave consent for their children to be included, but many were not adequately informed about the risks of chronic liver disease or the availability of gamma globulin. This case highlighted the lack of ethical guidelines in research involving human subjects and eventually led to the passage of legislation that required informed consent for scientific research projects.
