Public officials routinely defend vaccine mandates by invoking “the science.” We are told the benefits are clear, the risks minimal, and the tradeoffs settled. But that confidence depends on an assumption that no longer holds: that the scientific system producing these claims is reliable, transparent, and worthy of public trust.
It isn’t.
For years now, researchers across medicine and the social sciences have warned of a profound replication crisis. Large portions of published research—including studies in prestigious journals—cannot be replicated when independent teams attempt to reproduce the results. In pharmaceutical research, internal replication efforts by major drug companies have found success rates as low as 11 to 25 percent. In science, results that cannot be replicated are not merely uncertain; they are not dependable.
This crisis strikes at the heart of evidence-based policy.
The causes are well known. Publication bias favors positive findings and buries null or negative results. Financial incentives reward conclusions that support existing products and regulatory priorities. Industry-funded studies dominate the literature, while inconvenient data struggles to see daylight. Skepticism, the engine of scientific progress, is increasingly treated as heresy rather than virtue.
Even federal institutions have begun to acknowledge the problem. The National Institutes of Health has announced initiatives to fund independent replication studies, retesting influential findings instead of endlessly producing new ones. That is an implicit admission that much of what passes for settled science may rest on unstable ground.
This matters profoundly for vaccine policy, because mandates presume a level of certainty that the current scientific ecosystem cannot credibly provide.
Modern vaccine policy does not merely recommend medical products; it enforces compliance. It tracks uptake obsessively, celebrates coverage targets, and penalizes refusal. Yet the same system treats injury as an afterthought. Harms are primarily detected through passive post-marketing surveillance systems that underreport adverse events by design. Many injuries are never recognized as vaccine-related. Others are dismissed as coincidental. Still others emerge only years later, when causation becomes difficult or impossible to establish.
What results is not a true assessment of benefits and costs, but a profoundly asymmetric one. Benefits are aggressively articulated. Risks are minimized, obscured, or deferred.
That is not how honest science operates.
Importantly, this critique of the state of science does not rest on the claim that better data would justify mandates. It rests on the opposite. Even perfect data would not grant the state moral authority to compel medical interventions. Human beings are not laboratory subjects to be ordered into compliance for the sake of aggregate outcomes.
But the corruption of science makes mandates that much more indefensible. When uncertainty is high, dissent is suppressed, and harms are systematically undercounted, coercion becomes not merely unjust, but willfully negligent.
Recent history has made this impossible to ignore. We have seen how scientific institutions close ranks around preferred narratives, how dissenting experts are marginalized, and how public trust erodes when people sense that inconvenient facts are being managed rather than confronted. The result is not greater confidence in medicine, but widespread skepticism toward public health authorities themselves.
Science, at its best, is a tool for discovering truth. It advances through skepticism, replication, and humility. When those virtues are replaced with credentialism, censorship, and political pressure, science ceases to justify policy and instead becomes an instrument of power.
Mandates rely on the claim that “the science is settled.” But a scientific establishment in the midst of a replication crisis, riddled with bias, and resistant to independent verification, is in no position to make such claims, let alone to enforce them through coercive laws.
