You are a public health specialist commissioned to assess national infectious disease policy. Analyze the ethical and political difficulties inherent in implementing mandatory public health measures (e.g., vaccination mandates, quarantine laws). Offer a personal, jurisprudential perspective on where the state's authority should yield to individual autonomy, and suggest three highly contentious hypothetical scenarios for a public debate on coercive health policy. The report should be titled: Policy Paradox: Balancing Individual Liberty with Collective Health Imperatives.
