The rationale for identifying vulnerable subjects in a clinical trial centers around the ethical considerations of ensuring that participants can provide informed consent free from coercion or undue influence. Individuals influenced by expectations of benefits or retaliatory responses are considered vulnerable because their decision to participate may be distorted by their desire for potential benefits or fear of negative consequences, such as loss of access to medical care or employment.

Understanding this definition is essential, as ethical standards in research aim to protect those who might be less able to advocate for themselves in the context of clinical trials. These individuals may include populations such as the economically disadvantaged, those with diminished autonomy, or certain demographic groups susceptible to coercive pressures. In contrast, while physical injury, prior medical histories, or the need for special medical interventions are important considerations in clinical research, they do not inherently define vulnerability in the context of ethical research practices. This is why the identification of coercive influences and the ability to maintain autonomous decision-making is critical in this context.
