Jaclyn Peiser of The Washington Post details the Catholic Archdiocese of New Orleans’s moral opposition to the Johnson & Johnson vaccine because it used abortion-derived stem cells in production. The statement seemed to contradict a Vatican directive from last year that said Covid vaccines produced with those cells are permitted. Peiser writes, “There is a long-standing debate in the Catholic Church over accepting vaccines and treatments that use fetal tissue, centering on HEK293 cells, which are cloned from an aborted fetus from the early 1970s.”
