Ethics committee approval needs to be sourced before the study can recruit participants. An Ethics Review Board works to protect the rights, welfare, and privacy of human subjects. It usually includes a team of independent doctors, scientists, and community members. Their job is to review potential studies, weigh the risks and benefits of studies, and ensure that studies are safe and ethical. Ethical guidelines protect volunteers and ensure a study’s scientific integrity. Regulators created these guidelines primarily in response to past research errors and misconduct.
