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

Jacobson v. Massachusetts (1905): Upheld mandatory
smallpox vaccination, establishing state police power
-
Zucht v. King (1922): Upheld school vaccination
