The right to withdraw from controlled human infection studies: Justifications and avoidance

Area of Science:

• Bioethics
• Medical Research Ethics

Background:

• The right to withdraw from research without penalty is a global standard.
• Concerns about potential harms from withdrawal have led to challenges, particularly in controlled human infection (CHI) studies.
• These concerns highlight ethical dilemmas in research involving intentional participant infection.

Purpose of the Study:

• To provide support for preserving the right to withdraw from research without penalty.
• To demonstrate the justification of this right within the specific context of CHI studies.
• To address ethical challenges posed by participant withdrawal in sensitive research settings.

Main Methods:

• Analysis of individual freedoms and their alignment with research participation.
• Examination of U.S. law and globally relevant ethical principles.
• Review of strategies to manage withdrawal in research, including informed consent and incentives.

Main Results:

• The right to withdraw is generally justified, aligning with principles of autonomy and freedom.
• Withdrawal from CHI studies is typically justifiable, despite potential harms.
• Restricting the right to withdraw is not the optimal solution; proactive research design is preferred.

Conclusions:

• Preserving the right to withdraw without penalty is crucial, even in high-risk research like CHI studies.
• Addressing concerns about withdrawal involves careful study initiation and management, not limiting participant rights.
• Researchers should prepare for withdrawal, respect requests, and implement measures to minimize problematic withdrawals while upholding ethical standards.
