Answer:
The answer is - Nothing
Explanation:
IRB means Institutional Review Board. It is also known as an independent ethics committee whose main purpose is to protect the rights and welfare of human subjects used in research under its institution and making sure that research methods used are ethical. Since the incident has been handled according to protocol and the child is no longer upset then there is nothing left for the IRB to do as regards the report as long as the research was ethical and approved and got parental permission.
