In Jacobson v. Massachusetts, 197 U.S. 11 (1905), the U.S. Supreme Court upheld a Massachusetts state law mandating that everyone, adults and children, receive the smallpox vaccine. The law provided for a medical exemption for children, and the Court interpreted the law to allow for medical exemptions for adults also. The issue of religious objection to vaccination was not raised and not part of this case. This decision remains the leading precedent for laws requiring vaccination.
This decision was cited in the 5-4 ruling that upheld the federal ban on partial-birth abortion:[1]
This Jacobson decision is also known more generally for declaring that:
Justice John Harlan I wrote the decision, which Justice Oliver Wendell Holmes joined and later used in the notorious Buck v. Bell decision upholding mandatory sterilization of low-IQ women by the state of Virginia.
The court carefully emphasized, however, that vaccination could not be enforced against an individual to the detriment of his health:
โ | It is easy, for instance, to suppose the case of an adult who is embraced by the mere words of the act, but yet to subject whom to vaccination in a particular condition of his health or body, would be cruel and inhuman in the last degree. We are not to be understood as holding that the statute was intended to be applied to such a case, or, if it was so intended, that the judiciary would not be competent to interfere and protect the health and life of the individual concerned. | โ |
