Landmark legislation, court cases, and policy milestones.
The legal framework governing vaccines in the United States has evolved over more than a century. This page documents key legislative acts, Supreme Court decisions, and legal precedents that shape vaccine policy today.
Understanding this legal history helps explain the current landscape of vaccine mandates, injury compensation, and individual rights.
The legal foundation for vaccine mandates in the United States traces back to the 1902 smallpox epidemic. When Cambridge, Massachusetts enacted a mandatory smallpox vaccination ordinance, a pastor named Henning Jacobson refused to comply, arguing the law violated his liberty.
The case reached the Supreme Court in Jacobson v. Massachusetts (1905). The Court ruled 7-2 that states have the authority to require vaccination to protect public health. The decision established the principle that individual liberty can be restricted for the common good during public health emergencies.
Key precedent: States have "police power" to enact measures protecting public health and safety, even if they limit individual liberty.
By the 1970s, several factors converged to create a liability crisis for vaccine manufacturers:
This crisis threatened the stability of the U.S. vaccine supply and led Congress to consider federal intervention.
In response to the liability crisis, Congress passed the National Childhood Vaccine Injury Act (NCVIA) of 1986. The Act accomplished several things:
The VICP began accepting claims in 1988, providing a federal fund to compensate individuals injured by vaccines.
In Bruesewitz v. Wyeth, the Supreme Court ruled 6-2 that the VICP is the sole remedy for vaccine-related injuries. The case involved Hannah Bruesewitz, who suffered seizures and developmental delays after receiving a DTP vaccine in infancy.
The family's argument: The vaccine was defectively designed and should have been designed more safely. They sought to bypass the VICP and sue in state court.
Key ruling: The VICP preempts all state-law design defect claims against vaccine manufacturers. The Court held that Congress created the VICP precisely to provide a remedy for injuries "regardless of fault."
The COVID-19 pandemic prompted significant legal challenges regarding vaccine mandates:
These cases tested the boundaries of state police power and federal authority over vaccination requirements.
