The editors miss what may be the real reason for Europe's vaccine mismanagement: the precautionary principle. The rule strongly encourages caution among regulators working in any field with scientific uncertainty. First incorporated into the United Nations' 1992 Rio Declaration, the precautionary principle was later included as a foundational pillar of the European Commission's "Reach" Directive and was later enacted as a standalone statute by the European Parliament. The editorial states, "national governments are allowed to make their own safety rulings." That's often difficult in practice, especially among bureaucrats. The precautionary principle precludes the consideration of risk-benefit analysis. Fortunately for the U.S., President Clinton in 1993 signed an executive order precluding federal agencies from mandating "precaution" and instead standardized the use of risk-benefit analyses in rule-making. Nonetheless, the precautionary mindset has been nosing its way into U.S. federal, state and municipal laws, regulations and lives. Expect the covers to be lifted from this practice within much, if not all, of the Biden administration's decision-making (e.g., school openings). Imagine the state of the three vaccines now being injected into American arms if the precautionary principle had been imbedded into the cultures of our pharmaceutical industry and the Food and Drug Administration. There would have been no Operation Warp Speed.
