WASHINGTON (AP) — The Supreme Court on Monday rejected a challenge to a 2021 Connecticut law that eliminated the state’s longstanding religious exemption from childhood immunization requirements for schools, colleges and day care facilities.

The justices did not comment in leaving in place a federal appeals court ruling that upheld the contentious law. A lower court judge had earlier dismissed the lawsuit challenging the law, which drew protests at the state Capitol.

Connecticut law requires students to receive certain immunizations before enrolling in school, allowing some medical exemptions. Prior to 2021, students also could seek religious exemptions. Lawmakers ended the religious exemption over concerns that an uptick in exemption requests was coupled with a decline in vaccination rates in some schools.
