Підсумок	A waiver of informed consent permits research to proceed without obtaining prospective written or verbal consent from participants. This exception to the standard informed consent requirement applies to specific low-risk research scenarios where obtaining consent is impractical, unnecessary, or would compromise research validity. In the U.S., the regulations (45 CFR 46.116) specify four criteria that must be met for an IRB to approve a waiver; similar criteria apply in the UK (Research Ethics Committee) and EU jurisdictions. Waivers are not automatic; researchers must request them explicitly and justify them to the ethics committee, which determines whether the criteria are met.	Vulnerable populations are groups with limited capacity to protect themselves due to age, cognitive ability, institutional dependency, or social circumstances. Regulatory frameworks in the U.S. (45 CFR 46 Subparts B, C, D) and internationally identify specific vulnerable populations—children, prisoners, pregnant women, cognitively impaired individuals—and mandate additional ethical protections beyond standard informed consent. These protections include obtaining informed consent from surrogate decision-makers (parents, guardians), additional assurances of minimal risk, and enhanced monitoring for safety. Research ethics committees apply heightened scrutiny to studies involving vulnerable populations and may deny approval if special protections are inadequate.
