Ethical review is an important protective measure for research participants when conducting life sciences and medical research involving humans. "Exemption from ethical review" was proposed in The Measures for Ethical Review of Human Life Sciences and Medical Research Involving Humans issued in February 2023. To implement the exemption from ethical review within the permitted scope of laws and regulations, and to protect the privacy and rights of research participants when utilizing their data information and biological samples, multiple factors need to be considered, including the person responsible for exemption from ethical review, the conditions for exemption from ethical review, and the specific process for exemption from ethical review. As with other review procedures, exemption from ethical review also required the development of corresponding systems, implementation of responsibilities, and reliance on the construction of subject protection systems. It is hoped that this discussion can provide considerations for the implementation of exemption from ethical review.
