(from a school handbook) "SSPX Statement on Vaccination
Schools of the US District of the Society of Saint Pius X comply with vaccination policies of local health and education authorities while adhering to moral principles of the Roman Catholic Church. The Catholic Church does not oppose vaccinations in principle, but it does consider as morally illicit the development of vaccines from aborted fetal tissues. In 2005, the Vatican clarified the proper position of all Catholics on this matter, and the SSPX adheres to that declaration. Schools of the SSPX also support parental authority and freedom of choice, in matters not opposed to the moral law. If the state law does not mandate vaccination, neither do our schools. In the event of an outbreak of an infectious disease, our schools work closely with local and state officials to respond according to the guidelines prescribed by the governing authorities."
