Explanation:
IRB which stands for International Review Board is a form of committees that comprise or more members with different expertise or background and diversity whose responsibility includes performing reviews and authorizing human subjects study activities on behalf of various institutions.
Hence, in this case, IRB may waive or alter the regulatory elements of informed consent if it finds and documents a number of items, including the following amongst others:
1. Performing preliminary and continuing review of research study
2. Selecting which projects require a confirmation from other sources aside from the investigator that no material modifications have ensued since prior IRB review
3. Documenting results and activities to the investigator and the institution;
4. Defining which projects need review more often than yearly;
