Ethical justification of coercive public health policies must be premised upon their safety and efficacy

This article critically engages with Johnson et al. (2024), who argue that coercive public health policies require context-specific ethical justification. While Johnson et al. highlight four key principles—harm prevention, public interest, paternalism, and the duty of easy rescue—the present analysis contends that these ethical frameworks are insufficient unless safety, efficacy, proportionality, and necessity of the intervention are established beforehand. Drawing on examples from COVID-19 policies, including social distancing, surveillance measures, and vaccine mandates, the article demonstrates how weak or uncertain empirical evidence undermined ethical justifications for coercion. Cases such as low efficacy against transmission, underappreciated adverse events, and proportionality concerns reveal the dangers of treating empirical validity as an afterthought. The article concludes that coercive public health policies cannot be ethically defensible without robust prior evidence of effectiveness and safety. Ethical reasoning must therefore be grounded in empirical reality, with context-sensitive, localized approaches that ensure transparency, autonomy, and trust.
