Governments should require vaccination for certain diseases when necessary to protect public health.
Requiring vaccines in certain settings raises coverage to protective levels (herd protection) and reduces outbreaks, helping safeguard people who cannot be vaccinated.
Vaccination has controlled or eliminated deadly diseases—smallpox was eradicated and polio is near eradication—demonstrating population-level benefits.
U.S. courts have upheld reasonable vaccine requirements as constitutional when needed to prevent serious public-health threats.
Mandates can be seen as infringing bodily autonomy and personal medical decision-making, raising ethical concerns about proportionality and least-coercive alternatives.
Perceived coercion can erode public trust and fuel resistance, potentially undermining uptake and cooperation.
Nuanced approaches—including medical exemptions and targeted, setting-specific rules—can pursue public-health goals while accounting for individual circumstances.
Supporters argue mandates can achieve protective coverage, have a strong track record against deadly diseases, and are legally supported when narrowly tailored to serious threats. Opponents emphasize bodily autonomy, the risk that coercion undermines trust, and the value of tailored policies with appropriate exemptions. The debate weighs collective protection against individual liberty and the design of the least-coercive effective tools.
U.S. vaccine mandates date to the early 20th century, when the Supreme Court upheld smallpox vaccination requirements in Jacobson (1905). Since then, school-entry mandates and other targeted rules have been used for diseases such as polio and measles, with exemptions varying by jurisdiction. Recent debates focus on pandemic response, misinformation, and how to sustain high coverage while preserving public trust.
