The decision to receive a vaccination for COVID-19 "remains one of individual conscience in consultation with one's healthcare provider," the archdiocese said.
"The Archdiocese of New Orleans, in light of guidance from the Vatican, the United States Conference of Catholic Bishops, and The National Catholic Bioethics Center affirm that though there was some lab testing that utilized the abortion-derived cell line, the two vaccines currently available from Pfizer and Moderna do not rely on cell lines from abortions in the manufacturing process and therefore can be morally acceptable for Catholics as the connection to abortion is extremely remote," the archdiocese's statement read.
Ethicists have said that both the Pfizer and Moderna vaccines were "ethically uncontroversial" as their connection to abortions in the design phase were extremely remote. However, some lab tests for the vaccines were conducted using aborted fetal cell lines. The Johnson & Johnson vaccine, meanwhile, used aborted fetal cell lines in all phases.
"It is under the same guidance that the archdiocese must instruct Catholics that the latest vaccine from Janssen/Johnson & Johnson is morally compromised as it uses the abortion-derived cell line in development and production of the vaccine as well as the testing," the archdiocese said. This ethical problem is similar to that of the AstraZeneca vaccine, which also used an abortion-derived cell line in the development and testing of their product.
The archdiocese emphasized that "in no way does the Church's position diminish the wrongdoing of those who decided to use cell lines from abortions to make vaccines."
"In doing so, we advise that if the Moderna or Pfizer vaccine is available, Catholics should choose to receive either of those vaccines rather than to receive the new Johnson & Johnson vaccine because of its extensive use of abortion-derived cell lines."
