• Vulnerable means “subject to exploitation”Vulnerable means subject to exploitation
• Unequal power relationships between potential subjects and investigators/sponsors create the potential for exploitation
• Exploitation is wrong, and therefore we want t t/ id it i hto prevent/avoid it in research

• All vulnerable groups and individuals should receive specifically considered protection.

Medical research with a vulnerable group is only justified if the research is responsive to the health needs or priorities of this group and the research cannot be carried out in a non‐of this group and the research cannot be carried out in a nonvulnerable group. In addition, this group should stand to benefit from the knowledge, practices or interventions that result from the research.
