Children in clinical research

The participation of children in clinical trials is a practice which is typically more regulated than similar research on adults primarily due to the inability of children to give informed consent. The appropriate regulation of clinical trials on children is debated in medical ethics, where the benefits of testing the efficacy of medical treatments on children must be weighed against the harms such trials can cause to their child subjects.
