Mandates & Exemptions

From Jacobson v. Massachusetts to COVID-19 — the legal framework for vaccine requirements.

Vaccine mandates have been a feature of American public health law for over a century. This page traces the legal history of vaccine requirements in the United States, from early smallpox mandates through modern school requirements and COVID-19 policies.

Constitutional Foundation

The legal authority for vaccine mandates rests on two constitutional principles:

  • Police power: States have authority to enact laws protecting public health
  • Compelling interest: The government can require actions to protect community health

Key Supreme Court Cases

  1. Jacobson v. Massachusetts (1905): Upheld mandatory smallpox vaccination, establishing state police power
  2. Zucht v. King (1922): Upheld school vaccination requirements
  3. Bruesewitz v. Wyeth (2011): Ruled that VICP provides exclusive remedy for vaccine injuries
