TYLER, Texas — Because there are differing claims about the ethics of the Moderna COVID-19 vaccine, some clarifications need to be made, especially since phase III trials are concluding. What Catholics are willing to accept as ethical, despite unethical associations, for the first COVID-19 vaccines released publicly could influence the availability of more ethically sound options going forward.

Bishop Joseph Strickland in the Diocese of Tyler, who is known for his straight talk and defense of the faith, tweeted on Nov. 16: “Moderna vaccine is not morally produced. Unborn children died in abortions and then their bodies were used as ‘laboratory specimens.’ I urge all who believe in the sanctity of life to reject a vaccine which has been produced immorally.”

On Nov. 17, a Catholic News Agency (CNA) article compared Bishop Strickland’s position to that of bioethicists at the Charlotte Lozier Institute (CLI) and the National Catholic Bioethics Center (NCBC).

CLI lists the Moderna vaccine as “ethically uncontroversial,” a category they describe as having no connection to the use of cells from electively aborted fetuses. Dr. John Brehany, director of institutional relations at NCBC, told CNA that while Moderna “has some association with the use of cell lines from elective abortions, it is not responsible for that use, and its vaccine was not produced using HEK293 cells.”

The HEK293 referenced by Dr. Brehany is a fetal cell line derived from an aborted fetus in the 1970s. The claim that Moderna did not use HEK293 to produce the COVID-19 vaccine does not seem to line up with other available information.
