The U.S. Supreme Court has denied an emergency request from a Catholic mother in New York seeking permission to enroll her 5-year-old son in kindergarten without state-mandated vaccinations, according to reporting by ewtnnews.com.

The high court’s unsigned order did not address the merits of the underlying legal challenge. Justice Sonia Sotomayor referred the application to the full Court for consideration. Justices Samuel Alito and Neil Gorsuch indicated they would have granted the emergency stay, but their views were not enough to secure a majority.

The Legal Challenge

The mother, identified in court filings as Jane Doe, sought to enroll her son, C.F., at Waverly School in Eastchester for the September 2026 term. New York State eliminated religious exemptions from school vaccination requirements in 2019 following a measles outbreak. While medical exemptions remain available under state law, religious objections are no longer recognized as valid grounds for non-compliance.

Doe’s legal team previously sought temporary injunctions to block enforcement of the mandate against her family. Both a federal district judge in New York and a three-judge panel of the U.S. Court of Appeals for the 2nd Circuit denied those requests. Doe’s broader appeal remains pending before the 2nd Circuit.

State officials have argued that allowing religious carve-outs would undermine public health efforts to prevent disease transmission. Under current New York law, children with medical exemptions must remain home during outbreaks of vaccine-preventable diseases. Doe agreed to abide by such stay-at-home requirements if granted an exemption based on her religious beliefs.

Moral and Doctrinal Context

In April, Doe provided a statement to the school outlining her objections. She stated that her Catholic faith requires her to categorically refuse vaccination for herself and her children. Specifically, she cited the use of fetal cells from abortions in the original production of certain vaccines as a grave sin.

“The taking of an innocent human life is a grave sin. My Catholic beliefs have always held this,” Doe told the EWTN News.

Doe also expressed reservations about mixing blood with animal remains, aborted human tissue, or other foreign biological material. Her position reflects a strict interpretation of moral cooperation with evil, particularly regarding the origins of vaccine cell lines.

Church Teaching on Vaccination

The Catholic Church’s teaching on this issue is nuanced and distinguishes between moral obligation, prudential judgment, and the duty to oppose injustice. The 2008 instruction Dignitas Personae, issued by the Congregation for the Doctrine of the Faith, states that Catholics have a duty to oppose vaccine development methods that involve the use of aborted fetal cells.

However, the same document permits the use of vaccines developed with such cell lines when no alternative exists and there is a serious health reason. The Church teaches that parents may use these vaccines while simultaneously working to ensure safer alternatives are developed.

A 2020 note from the Congregation for the Doctrine of the Faith clarified that vaccination is not a moral obligation in itself and must be voluntary. It emphasized that individuals should make decisions based on their conscience, informed by medical evidence and moral principles.

The Catechism of the Catholic Church affirms the right to act according to conscience. “Man has the right to act in conscience and in freedom so as personally to make moral decisions,” the Catechism states. “He must not be forced to act contrary to his conscience. Nor must he be prevented from acting according to his conscience.”, as first reported by the EWTN News

While the Supreme Court declined to intervene at this stage, the underlying appeal continues in the federal appellate courts.
